Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application is a divisional application of U.S. application Ser. No. 15/807,411, filed on Nov. 8, 2017, which claims priority to U.S. Provisional Patent Application No. 62/419,837, entitled “Systems and Methods for Pre-Scheduling In Virtual Queuing Systems,” filed Nov. 9, 2016; and to U.S. Provisional Patent Application No. 62/419,833, entitled “Systems and Methods for Automatically Monitoring and Dynamically Adjusting A Queue,” filed on Nov. 9, 2016, which are incorporated by reference in their entireties herein for all purposes. 
    
    
     BACKGROUND 
     The present disclosure relates generally to the field of amusement parks. Specifically, embodiments of the present disclosure relate to techniques to manage amusement park experiences, including queuing for attractions. 
     Since the early twentieth century, amusement parks have substantially grown in popularity. In order to address this increasing demand, amusement parks have been expanding by adding attractions and space. The addition of attractions (e.g., rides, restaurants, shops, and shows) generally provides an amusement park with additional capacity to handle a larger number of guests. However, the additional attractions also typically provide potential guests with an incentive to visit the amusement park. Thus, while a particular amusement park may add additional capacity, the additional capacity does not always result in an increased ability for guests to participate in park entertainment (e.g., shopping, viewing shows, riding rides) or reduced wait times for attractions. This is because there is often a corresponding increase in attendance. Further, due to operating efficiencies, it is often desirable to limit the availability of attractions during low attendance times. Thus, queuing for attractions, which may limit participation in park activities, is a perennial issue for amusement parks. 
     While guests have demanded bigger, better, and more elaborate attractions, they also require and expect a positive overall experience. Providing a positive overall experience for amusement park guests entails addressing certain issues related to queuing for attractions. Indeed, it is now recognized that park guests can be deterred from returning to a particular amusement park due to negative experiences with queue waiting times. Further, guests may be prevented from accessing amusement park businesses (e.g., shops) due to time spent waiting in queues. Indeed, in the past, guests have waited hours in line to experience some of the more popular attractions at an amusement park. Additionally, it is now recognized that park capacity does not always result in efficient guest utilization of that capacity due to individual guest preferences for certain attractions over others. Accordingly, it is now recognized that it is desirable to improve amusement park queuing systems and methods.

     Certain embodiments commensurate in scope with the originally claimed subject matter are summarized below. These embodiments are not intended to limit the scope of the disclosure, but rather these embodiments are intended only to provide a brief summary of certain disclosed embodiments. Indeed, the present disclosure may encompass a variety of forms that may be similar to or different from the embodiments set forth below.

     DETAILED DESCRIPTION 
     Theme park or amusement park attractions have become increasingly popular, and various amusement park attractions have been created to provide passengers with unique motion and visual experiences. Guests entering the various amusement park attractions may utilize a virtual queuing system that places the guests in a virtual queue rather than a physical queue, which allows the guests to enjoy other features of the amusement park while their position in the virtual queue advances. To help guests plan their day, the virtual queuing system may estimate wait times (e.g., a length of time before the guest may enter the attraction) and provide a reminder to the guest that the time to enter the attraction is approaching. However, in determining wait times for guests for each attraction, certain virtual queuing systems assume average wait times or average guest return rates, or may utilize predetermined or preconfigured wait times for a static number of rides (e.g., guest-accepting features of the attraction, such as individual ride vehicles, individual lanes of a multi-lane slide, individual tracks of a multi-track attraction, etc.) within a specific attraction. Using data based on a static number of rides to determine wait times may fail to dynamically react to queue conditions (e.g., ride closures and openings at an attraction). Indeed, such virtual queuing systems may provide inaccurate wait times for guests, which may lead to excessive or deficient wait times and cause inefficient operation of the amusement park attractions. 
     With this in mind, certain embodiments of the present disclosure relate to virtual queuing systems that determine wait times by monitoring and/or dynamically evaluating the virtual queue based at least on queue conditions and scheduling information for the amusement park attraction. Embodiments of the present disclosure facilitate dynamically modifying queue operations in response to received feedback associated with the wait times. Specifically, certain embodiments of the present disclosure relate to determining wait times by monitoring and evaluating dynamic variations in open/close times for various attractions (or various rides within a specific attraction) in addition to queue conditions when determining wait times for attractions. In particular, the virtual queue system may be configured to utilize scheduled times for each attraction, current or real-time guest throughput for an attraction, estimated guest throughput in the future, a historical throughput for each attraction, and/or historical queue wait time information to accurately determine wait times for a particular attraction to avoid communicating inaccurate wait times to guests. In this manner, the virtual queuing system may help to prevent ride underutilization, ride overcrowding, and/or inefficient use of ride resources over a period of time. Additionally, certain embodiments of the present disclosure relate to automatically or dynamically modifying queue operations or the actual virtual queue in response to deficient or excessive wait times to further prevent inefficient operations, ride underutilization, ride overcrowding, and/or wasting ride resources over a period of time. Further, the virtual queuing system may be configured to monitor and track how the guests transition or move throughout the queue to provide for a more granular control of the virtual queue. Accordingly, based on a more granular control of the virtual queue, the virtual queuing system may be configured to have automatic and dynamic control of attraction access, thereby preventing ride starvation, overcrowding, or wasting other ride resources. 
       FIG. 1  is a schematic representation of a theme park  110  with at least one amusement park attraction  112  that may be accessed via a virtual queue that is controlled by a virtual queue system  114 . Certain attractions  112  may feature a plurality of rides  118 . For example, in the depicted embodiment, a water slide attraction  112   a  may include multiple lanes or slides (e.g., shown as rides  118   a ,  118   b , and  118   c ) that are accessed via a single virtual queue, which permits access to a loading area  116  for the guests. That is, the guests assume a position in a virtual queue for the attraction  112   a  to enter the loading area  116 . Once in the loading area  116 , the guests are distributed between separate slides (i.e., rides  118   a ,  118   b , and  118   c ) to experience the attraction  112 . Accordingly, in the depicted embodiment by way of example, the attraction  112   a  is capable of accommodating multiple guests (e.g., two, three, or more) at a time. However, the guests may enter their assigned ride  118  at different rates, leading to dynamically changing real-time guest throughput rates for each ride  118  of the multi-ride attraction  112 . For example, certain guests may be more hesitant than others, leading to a temporarily slower real-time guest throughput rate in one ride  118  relative to another. Further, the ride operators may have different efficiencies in distributing and loading guests into their respective rides  118 . Accordingly, determining a total guest throughput for a multi-ride attraction  112  may be complex and may involve taking into account different real-time guest throughput rates at each individual ride  118  of the attraction  112  to determine a total guest throughput for the attraction  112 . 
     While the depicted embodiments are shown in the context of water attractions, such as water slides, it should be understood that other multi-ride attractions  112  are contemplated. Further, the rides  118  of an individual attraction  112  may include any suitable number of rides  118  (slides, tracks, paths vehicles, etc.) accommodating any suitable number of guests that are nonetheless accessed via a single virtual queue for the attraction  112 . In addition, the theme park  110  may also feature other attractions  112  that do not include multiple rides  118 , e.g., single ride attractions  112 . 
     In one embodiment, via the virtual queue system  114 , guests are assigned a position in a virtual queue for the amusement park attraction  112  after submitting a request from a guest-associated device  120  (e.g., smart phone, guest wrist band) or a guest kiosk  121  and need not physically queue to enter the attraction  112  until a designated time. Thus, guests using a virtual queue may spend less time waiting in lines during their visit to the theme park  110 . Additionally, data from the virtual queue provides guidance to the theme park for scheduling ride openings and closures to optimize guest throughput and amusement park attraction efficiency. 
     In some embodiments, the virtual queue system has a plurality of virtual queues, each corresponding to a separate amusement park attraction (e.g.,  112   a  and  112   b ). To aid guests in determining which virtual queue to enter, the virtual queue system  114  is configured to output a wait time signal  122  indicating current wait times for each amusement park attraction  112 . A display unit  126  may be configured to receive the wait time signal  122  and display the current wait times for guests within the theme park  110 . The display unit  126  may be a central display unit configured to display the current wait times corresponding to a plurality of amusement park attractions. However, in some embodiments, the display unit  126  may be a localized display unit configured to display a current wait time for a single amusement park attraction. In another embodiment, a guest-associated device  120  (e.g., smart phone, guest wrist band, guest tracker, etc.) may receive the wait time signal  122  and display the current wait times for a guest (e.g., text message, smart phone app. notification, etc.). 
     In certain embodiments, the wait time signal  122  transmits the current wait time, a guest wait time (i.e., a wait time for an individual guest in the virtual queue), or some combination thereof. The current wait time indicates the time that an unqueued guest should anticipate waiting before entering the amusement park attraction  112  if joining the virtual queue at that time. In contrast, the guest wait time indicates the time that an individual guest, already having a position in the virtual queue, still has to wait until entering the amusement park attraction  112 . Thus, the guest wait time corresponds to a specific position of an individual guest already queued in the virtual queue, whereas the current wait time corresponds to the next available position (i.e., an unassigned position) in the virtual queue. 
     In an embodiment, the virtual queue system  114  determines wait times based at least on scheduling information or ride schedule data for the attraction  112 . Ride schedule data includes planned ride openings and closures for the attractions  112  at specified times during theme park hours as well as dynamic openings or closures in response to desired crowd flow. In the depicted embodiment, the attraction  112   a  includes three rides  118   a ,  118   b , and  118   c  (e.g., slides, ride vehicles, seats, etc.) accessed by a single virtual queue. One or more of the three rides  118  may close during park hours, e.g., at specified times, determined by or included in a ride schedule, for the purpose of increasing attraction efficiency. For example, each of the three rides  118  may have an average historical guest throughput potential of one hundred and twenty guests per hour. Thus, in the depicted embodiment, a second ride  118   b  and a third ride  118   c  may close during times of the day when guest throughput is historically low. When guest throughput is low, opening only a first ride  118   a  may allow the attraction to maintain sufficient guest throughput to keep the wait times low while requiring fewer employees to operate the attraction  112   a . In contrast, when guest throughput is historically high, the attraction may open the second ride  118   b  and the third ride  118   c  to increase guest throughput in order to minimize the wait times. Because opening and closing rides  118  of the attraction  112  dynamically changes real-time guest throughput and future guest throughput during the closure times, having the virtual queue system  114  determine wait times based at least on scheduling information may provide more accurate wait times for guests. Thus, scheduling information regarding dates, times, and other details as to ride closures and openings is sent to a virtual queue controller  130  of the virtual queue system  114 . In certain embodiments, scheduling information is automatically transmitted to the virtual queue controller  130  from a theme park database. In other embodiments, a user may manually enter or modify scheduling information for the virtual queue controller using an operator interface  132 . 
       FIG. 2  is a flow diagram of a method  234  of determining the current wait time (e.g., for an as-yet unqueued guest) and the guest wait time for guests in the virtual queue of the attraction  112  using a virtual queue system  114  in accordance with present embodiments. The method includes providing ride schedule data for the attraction  112  to the virtual queue controller  114 , wherein the ride schedule data includes specified times for the one or more rides to open and close (block  236 ), and wherein opening and closing the one or more rides increases or decreases estimated guest throughput of the attraction accordingly, calculating variable guest throughput data, wherein the variable guest throughput data is calculated based at least on the ride schedule data and historical guest throughput data for the attraction (block  238 ), determining a current wait time for the next available position in a virtual queue for the attraction  112  based on at least the next available position and the variable guest throughput data (block  240 ), outputting a wait time signal to a display unit, a guest-associated device, or a combination thereof, indicating the current wait time for the next guest to queue for the attraction  112  (block  242 ), assigning a guest to a position in a virtual queue for an attraction in response to a guest queue request (block  244 ), determining a guest wait time for the guest based on at least the position in the virtual queue and the variable guest throughput data (block  246 ), and outputting a wait time signal to the guest-associated device indicating the guest wait time (block  248 ). Details of the aspects of the method  234  will be discussed in further detail herein with respect to related system features. 
     In certain embodiments, the method  234  includes the step of further calculating the variable throughput data based on current or real-time guest throughput data. In some embodiments, the method  234  includes the step of providing queue condition data for the attraction  112  to a virtual queue controller  114 , wherein the queue condition data includes at least current guest throughput data for the amusement park attraction. 
     In certain embodiments, the virtual queue controller  130  is configured to continuously or periodically determine the guest wait time and to continuously output the wait time signal to the guest-associated device  120  indicating an updated guest wait time. In other embodiments, the virtual queue controller  130  is configured to determine the guest wait time in response to an update request from the guest. The virtual queue controller  130  may limit the number of update requests that a guest may issue. In other embodiments, the virtual queue controller  130  may limit the rate at which guests may issue update requests. In some embodiments, the virtual queue controller  130  is configured to output the wait time signal when the virtual queue controller determines that the guest wait time has changed by more than a pre-determined amount of time. For example, the virtual queue controller  130  may output a new wait time signal when the guest wait time has changed by more than two minutes. 
       FIG. 3  is a block diagram of the virtual queue system  314 . The virtual queue system includes a virtual queue controller  330  (e.g., the virtual queue controller  130 ) in communication with the guest-associated device  320 , the display unit  326 , or a combination thereof. To enter the virtual queue for an attraction  112 , the guest-associated device  320  transmits a queue request signal  350  to the virtual queue controller  330  in response to an input from a guest. The virtual queue controller  330  receives the queue request signal  350 , determines a wait time for the guest, and outputs a wait time signal  322  to the guest-associated device  320 , the display unit  326 , or a combination thereof. The guest-associated device  320  and the display unit  326  are configured to receive the wait time signal  322  and display the wait time for the guest. To enable these communications, the guest-associated device  320 , the display unit  326 , and the virtual queue controller  330  may include communications circuitry  352 , such as antennas, radio transceiver circuits, signal processing hardware and/or software (e.g., hardware or software filters, A/D converters, multiplexer amplifiers), or a combination thereof. The communications circuitry  352  may be configured to communicate over wired or wireless communication paths via IR wireless communication, satellite communication, broadcast radio, microwave radio, Bluetooth, Zigbee, Wifi, UHF, NFC, etc. Such communication may also include intermediate communications devices, such as radio towers, cell towers, etc. 
     In certain embodiments, the virtual queue controller  330  may include a memory device  354   a  storing instructions executable by a processor  356   a  to perform the methods and control actions described herein. For example, the processor  356   a  may execute instructions for dynamically evaluating virtual queue conditions and determining wait times for guests based on guest throughput inputs  358  and ride schedule data inputs  360  received by the virtual queue controller  330 . The ride schedule data inputs may be received through user input, from a memory storage, and/or through cloud services. The virtual queue controller  330  may receive scheduling (or re-scheduling) information in real-time, and may be configured to update wait times based on the updated schedule. In certain embodiments, the virtual queue controller  330  may receive and utilize additional inputs in combination with the ride schedule data inputs  360  and guest throughput inputs  358  when determining wait times. 
     Further, in certain embodiments, the processor  356   a  may utilize historical queue condition data inputs  362  (e.g., historical weather information, previous guest behavior within a particular ride/attraction, calendar information (e.g., time of day, day of week, holidays, etc.), demographic information, number of guests within a group(s), and so forth) in combination with the ride schedule data inputs  360  and/or guest throughput inputs  358  when determining wait times. For example, the processor  356   a  may account for historically slower crowds or colder seasons conditions when providing wait times. As a further example, in certain embodiments, the processor  356   a  may utilize various characteristics of the guests (e.g., type, gender, age, number, etc.) within the queue, in combination with the ride schedule data inputs  360  and guest throughput inputs  358 , in order to determine wait times. While the guest throughput inputs  358 , ride schedule data inputs  360 , and historical queue condition data inputs  362  are depicted as being received via an operator interface  332 , it should be understood that the various inputs to the virtual queue controller  330  may be received from other components of the system  314 . In one embodiment, the guest throughput inputs  358  comprise real-time throughput information that is transmitted to the virtual queue controller  330  based on guest-associated device  320  interaction with a check-in or tap-in device or by passing through a gate at each attraction  112 . For example, as each guest enters the attraction  112 , the associated guest identification information from the guest-associated device  320  is read by a reader comprising communication circuitry and associated with the attraction. In an embodiment, each individual ride  118  of the attraction  112  is configured to provide guest identification from a reader positioned at a top or start of each ride  118 . The guest identification information, associated attraction  112  information and/or ride  118  information, and timestamp may be provided to the virtual queue controller  330  as inputs to determine dynamic real-time guest throughput (e.g., guests/hour). Further, the attraction  112  may also include a reader at a ride exit to track total time through the ride  118  as a variable in determining real-time guest throughput. In another embodiment, the real-time guest throughput may be based on operator information. For example, a ride operator may track a number of guests and provide guest numbers periodically to the operator interface  332 . Further, the virtual queue controller  330  may store the guest throughput information to update historical queue condition inputs  362  using acquired guest throughput data. 
     The processor  356   a  of the virtual queue controller  330  may include one or more processing devices, and the memory may include one or more tangible, non-transitory, machine-readable media. By way of example, such machine-readable media can include RAM, ROM, EPROM, EEPROM, or optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to carry or store desired program code in the form of machine-executable instructions or data structures and which can be accessed by the processor or by other processor-based devices (e.g., mobile devices). For example, the virtual queue controller  330  may be accessed by an operator interface  332  (e.g., a computer-based workstation or a mobile device, and/or may include an input/output interface  364  and a display). 
     In certain embodiments, the guest-associated device  320 , having a processor  356   b  and a memory  354   b , may be a personal guest device (e.g., smart phone, tablet, laptop, etc.) or a park queue device assigned to guests (e.g., smart wrist bands, portable communication devices, etc.). Park queue devices include a program for viewing wait times and sending queue requests. Guests using personal guest devices may be given access to the program (e.g., web based program, smart phone app., downloadable program, etc.). For example, an admission ticket to the theme park or a confirmation email may include details for finding the program, as well as a username, a passcode, or a combination thereof, for accessing the program. Personal information associated with a guest (height, weight, age, and other demographics) may be linked to the username and/or passcode, such that the guest identification information may be transmitted with the queue request signal. A guest using park queue devices may have their guest information uploaded to the park queue device when the device is assigned to the guest. The virtual queue controller  330  may utilize guest identification information determining wait times as provided herein. 
     In certain embodiments, the system may include a queue station (e.g., guest kiosk  121 ) that includes a processor and a memory, and is configured to provide an additional resource for guests to view times and send queue requests. Guests may access queuing functionality on the queue station using a form of guest identification (e.g., username, passcode, card, RF wristband, personal information, etc.). Queue stations may be disposed at various locations around the theme park  110 . In some embodiments, at least one queue station is disposed proximate an entrance of each attraction  112 , such that guests are provided a means to queue for the attraction  112  at a location proximate the attraction  112 . In some embodiments, queue stations may only permit guests to queue for the attraction  112  most proximate the queue station. In other embodiments, general queue stations are located throughout the theme park  110 , which may be used to queue for attractions  112  in the theme park  110 . 
     In certain embodiments, the display unit  326  is configured to receive the wait time signal  322  from the virtual queue controller  330  and display current wait times for the attractions  112 . In some embodiments, at least one display unit  326  is disposed proximate an entrance of each attraction  112 . The display unit may be configured to display only the current wait time for the attraction  112  most proximate the display unit. In other embodiments, general display units are disposed in general locations (e.g., eating areas, walking paths, etc.) around the theme park  110 . General display units may display current wait times for a plurality of attractions  112 . 
       FIG. 4  is a block diagram of the virtual queue system  414  having a monitoring device  466 . In the present embodiment, the monitoring device  466  may have communication circuitry  452   d  to establish communication with the virtual queue controller  430 . The monitoring device  466  may also have a processor  456   c  and a memory device  454   c . The monitoring device  466  is configured to monitor and/or determine current queue conditions and output a queue condition signal  468  to the virtual queue controller  430 . In some embodiments, the attraction  112  has both a physical queue and a virtual queue. In such embodiments, a guest first enters a virtual queue before entering the physical queue. The physical queue provides a buffer queue or a standby area for the attraction  112  to increase efficiency of the attraction  112 . For example, in the event that a guest does not arrive to the attraction  112  at the time designated by the virtual queue system  414 , without a physical buffer queue, it is possible that no guest would be present to fill the position of the absent guest. Therefore, at least one ride  118  of the attraction  112  may proceed with less than maximum occupancy of the ride, thereby, decreasing efficiency of the attraction  112 . However, using both a physical queue and a standby area, a plurality of guests may be present at the attraction  112  to fill the ride to max occupancy, even when a guest does not arrive on time. In certain embodiments, the monitoring device  466  is configured to monitor current queue conditions of the physical queue. However, the monitoring device  466  may be configured to monitor current queue conditions of the physical queue, the virtual queue, or a combination thereof. Further, in certain embodiments, the attraction  112  may be implemented without a physical queue. 
     In certain embodiments, the monitoring device  466  may be configured to monitor or determine current queue conditions, including, but not limited to, the length of the queue, number of guests in the queue, flow rate of the guests entering and exiting the queue, particular individuals within the queue (e.g., identify guests in the queue), number of sub-queues within the queue, types of guests within the queue, and so forth. In certain embodiments, the monitoring device  466  may monitor particular locations (e.g., geographical location, queue zones, etc.) within the queue and output the number of guests in each particular location to the virtual queue controller. In certain embodiments, the monitoring device  466  may monitor guests not just at the beginning or end of the queue, but may also monitor whether guests leave the queue in the middle of the queue. In certain embodiments, the monitoring device  466  may determine various characteristics of the guests (e.g., type, gender, age, number, etc.) within the queue and output that data to the virtual queue controller  430  to track and record historical throughput data associated with the queue as it relates to the attraction  112 . 
     In certain embodiments, the monitoring device  466  includes a counting mechanism  470  configured to monitor queue conditions. For example, the number of guests within the queue may be monitored with a counting mechanism  470 , which may be a manual system and/or may include one or more sensors disposed proximate to the queue. In other embodiments, the monitoring device may include at least one sensor  472  (e.g., optical sensors, mechanical treadles, RF sensing systems, etc.) disposed physically proximate to the queue, and communicatively coupled to the virtual queue controller  430 . The sensors  472  may provide continuous feedback to the virtual queue system  414  associated with current queue conditions. For example, in situations where guests each carry RF identification, RF sensors associated with the monitoring device may be configured to monitor when the particular guest(s) enters and exits the queue and output that data to the virtual controller. As a further example, the sensors  472  may be configured to recognize individual guests at the entrance and exit of the queue and continuously output that information to the virtual queue controller, such that various conditions of the queue (e.g., wait time, queue length, etc.) may be calculated based on length of time individual guests spend within the queue. 
     Based on the received feedback, the virtual queue system  414  may be configured to dynamically respond to current queue conditions. In certain embodiments, the virtual queue system  414  may include the functionality to automatically remove a guest from the virtual queue based on one or more factors (e.g., been in the queue for an extended period of time past current queue wait time, guest is seen at an unexpected location within the queue, guest enters another queue, guest is recognized outside of the queue, etc.). In certain embodiments, the virtual queue system  414  may virtually monitor and dynamically adjust a plurality of queues (or sub-queues), and may be configured to correlate the data for a variety of queues when calculating or determining current queue conditions. 
     In certain embodiments, the virtual queue system  414  may utilize the feedback received from the monitoring device  466  to calculate other queue conditions. The virtual queue system  414  may calculate various factors or variables, such as, but not limited to, length of the virtual queue, current or real-time guest throughput, maximum attraction throughput, historical information related to queue conditions and responses (e.g., historical guest throughput), length of time that the queue is in different states (overfill state, under-fill state, starvation state, overcrowding state, etc.), and so forth. For example, based on the number of guests within the queue and/or the flow rate of the guests entering or exiting the queue, the virtual queue system  414  may calculate current wait times, guest wait times, current attraction capacity, and so forth. In particular, the virtual queue system  414  may be configured to determine accurate real-time information related to the queue system and queue conditions, based at least in part on the continuous feedback received from the monitoring device  466 . 
     In another embodiment, in response to determined wait times for guests in the virtual queues and/or physical attraction access areas, the virtual queue system  414  may be configured to output a queue modification signal  474 . Specifically, the virtual queue system may be configured to dynamically respond to deviations of the calculated wait times for guests from a wait time range by outputting a queue modification signal  474 . 
     In certain embodiments, the queue modification signal  474  is configured to temporarily disable the ability to add a guest to the virtual queue for an attraction  112  when the wait time for the attraction is longer than a maximum limit of the wait time range. For example, when the virtual queue is deemed too long by the virtual queue controller  430 , the virtual queue controller is configured to output the queue modification signal  474  to the guest-associated device  420  (e.g. smart phone, guest kiosk, etc.). The queue modification signal  474  is configured to transmit instructions to a queue program, on the guest-associated device  420 , to disable an option to send a queue request for the attraction  112 . Additionally, the queue modification signal  474  may include instructions to display a message in relation to disabling a portion of the queue program. Once wait times of the virtual queue fall back down to a length of time within the wait time range, the virtual queue controller  430  may be configured to send a resume signal  476  to enable the option to send queue requests. 
     In certain embodiments, the queue modification signal  474  includes instructions to notify guests of a shorter than average queue time for an attraction  112  when the wait time for the attraction is shorter than the minimum limit of the wait time range. For example, the queue modification signal  474  may include instructions for the guest-associated device to display a message indicating that the attraction  112  has a short wait time. In some embodiments, the queue modification signal  474  may include instructions to activate a quick queue option in the program on the guest-associated device  120 . For example, the quick queue option may activate a pop up message the screen that indicates that the virtual queue has a short wait time. Additionally, the pop up message may include a button configured to immediately enter the guest into the virtual queue for the attraction  112 . In certain embodiments, the virtual queue controller  430  is configured to send the queue modification signal  474  to guest-associated devices  420  linked to guests that have experienced fewer attractions  112  during that day than other guests at the theme park  110  before sending the queue modification signal to the other guests, thereby giving a first opportunity to enter the virtual queue to individuals who have experienced fewer attractions  112 . In certain embodiments, the program includes an option to dismiss messages activated in response to the guest-associated device receiving the queue modification signal  474 . However, once wait times of the virtual queue rise up to a length of time within the wait time range, the virtual queue controller is configured to send the resume signal to automatically dismiss notifications from the queue modification signal. 
     In certain embodiments, the virtual queue controller is configured to send an attraction modification signal  478  to an amusement park operator device  480  in response to the wait times longer than the maximum limit or shorter than the minimum limit of the wait time range. The attraction modification signal is configured to send instructions to an amusement park operator to open and/or close rides of an amusement park ride  118  to adjust current guest throughput in response to the wait times. In addition to disabling the virtual queue or sending notifications, dynamically opening and closing rides  118  of an attraction  112  may further increase amusement park attraction efficiency. 
       FIG. 5  is a graph showing the wait times  582  and a wait time range  584  for the virtual queue. The wait time range provides a minimum wait time  586  and a maximum wait time  588  for acceptable wait times at particular times, e.g., whereby wait times between the minimum wait time  586  and the maximum wait time  588  may bound a predetermined desired wait time range. When wait times  582  as calculated or estimated by the virtual queue controller (e.g., virtual queue controller  430 ) as provided herein fall below the minimum wait time  586  or rise above the maximum wait time  588 , the virtual queue controller  430  is configured to output the queue modification signal  474 . In certain embodiments, the virtual queue controller  430  calculates the wait time range  584  based at least on historical throughput data. The virtual queue controller  430  may determine an average wait time  590  for an attraction  112  for each time slot of a day using the historical throughput data. The virtual queue controller  430  may determine a plurality of average wait times, wherein an average wait time is calculated for each time slot of each day of a week, month, year, etc. For example, the virtual queue controller  430  may calculate an average wait time for an attraction  112  at 10 a.m. by averaging all historical throughput data for the time slot of 10 a.m. However, in other embodiments, the virtual queue controller  430  calculates an average wait time for Monday at 10 a.m. by averaging all historical throughput data for every Monday at 10 a.m. Additionally or alternatively, the virtual queue controller  430  may further utilize historical queue condition data (e.g., historical ride schedule data, historical guest throughput, weather data, guest behavior, calendar information, demographic info, number of groups of guests, size of groups of guests, etc.) in determining the plurality of average wait times  590 . 
     In certain embodiments, the virtual queue controller  430  may calculate the wait time range  584  by adding a wait time buffer to the average wait time  590 . For example, the virtual queue controller  430  may calculate average wait times for 9 a.m., 11 a.m., 1 p.m., and 3 p.m. to be five, twenty, forty, and thirty-five minutes respectively. The virtual queue controller  430  may provide a five minute wait time buffer to the average wait times to calculate the wait time range. Thus, the wait time ranges at 9 a.m., 11 a.m., 1 p.m., and 3 p.m. are 0-10 minutes, 15-25 minutes, 35-45 minutes, and 30-40 minutes respectively. In other embodiments, the virtual queue controller  430  may calculate the wait time range  584  using a dynamic wait time buffer. The dynamic wait time buffer may change a length of time of the wait time buffer at different time slots of a day. For example, a wait time buffer at 9 a.m. may be five minutes, while a wait time buffer at 1 p.m. may be fifteen minutes. In other embodiments, the dynamic wait time buffer includes a longer wait time buffer between the average wait time and the maximum limit than the wait time buffer between the average wait time and the minimum limit. In some embodiments, the dynamic wait time buffer may be determined using historical throughput data, operator input, etc. 
     In certain embodiments, the wait time range may be set based on inputs receive by the virtual queue controller  430 . In some embodiments, the virtual queue controller  430  is configured to receive an input from the operator interface  332 . An operator may transmit instructions for the virtual queue controller  430  to set specific wait time ranges using the operator interface  332 . The operator may set static or dynamic wait time ranges. In some embodiments, an operator may set a wait time range independent of historical throughput data. For example, in the event that an attraction  112  is temporarily under staffed, an operator may adjust the wait time range  584  of the attraction  112  to decrease guest throughput of the attraction  112  until the attraction  112  is properly staffed. In another example the operator may adjust the wait time ranges  584  for a plurality of attractions  112  to encourage guests to queue for the particular attraction  112 , in order to prevent overcrowding of other attractions  112  or locations. 
     In certain embodiments, the virtual queue controller  430  may determine wait times  582  for a position in the virtual queue based on variable guest throughput data and ride schedule data. Generally, the virtual queue controller  430  calculates a variable guest throughput based at least on current guest throughput data, historical throughput data, historical ride schedule data, etc. The variable guest throughput data represents an expected guest throughput for a single ride  118  of the attraction  112  for each time slot during park hours. The virtual queue controller  430  is configured to predict expected guest throughput data at least based on deviations of current guest throughput data with respect to historical throughput data and other queue conditions. To accurately analyze throughput variations and prevent scheduling variations from skewing the calculation, the current guest throughput data and the historical throughput data are first divided respectfully by the number of rides currently open and the number of rides historically open (i.e., to determine current guest throughput data and historical guest throughput data for a single ride). Further, the virtual queue controller  430  is configured to dynamically multiply the expected guest throughput data for a single ride according to the ride schedule data to determine an expected guest throughput for each time slot during the park hours. The virtual queue controller  430  is configured to utilize the expected guest throughput, current queue conditions (e.g., number of guests in queue, etc.) in relation to the guest position to determine wait times. 
     As an exemplary embodiment, in certain situations, an attraction  112  may include one or more rides  118  that open and close at different times throughout the day. For example, a first ride  118   a  of an attraction  112  may open concurrently with the opening of theme park  110 , and a second ride of the attraction  112  may open an hour after the theme park  110  opens. Each ride of the attraction  112  may have a throughput of 120 guests per hour. Features of the present disclosure enable the virtual queuing system to utilize the scheduled open/close times of each ride during the day to determine wait times for the attraction  112 . For example, the virtual queuing system accounts for the delayed opening time of the second ride  118   b  when determining a wait time for the attraction  112 . In this manner, the virtual queuing system may provide an accurate wait time for the attraction  112 , rather than an artificially low wait time that would be associated with the cases of all rides  118  being open. In other words, when one or more of the rides  118  are closed, the estimated total guest throughput of the attraction  112  will be reduced. Further, the virtual queuing system  114  accounts for the one hour delay in opening the second ride  118   b  during wait times assigned before the second ride  118   b  is scheduled to open. 
     For example, in an embodiment, a guest requests a position in the virtual queue such that the guest wait time for the attraction  112  encompasses or overlaps a first time period in which a subset of the rides  118  are closed and a second time period in which all of the rides  118  are open. That is, some or all of the closed rides  118  are opened while the guest is in the virtual queue. Accordingly, the attraction  112  has an estimated lower guest throughput during the first time period and an estimated higher guest throughput during the second time period. By using the lower guest throughput and the higher guest throughput, a more accurate guest waiting time may be determined. In this manner, the virtual queuing system may avoid periods of ride starvation (when artificially high wait times are reported), or ride overcrowding (when artificially low wait times are reported). 
     In one embodiment, for the attraction  112 , historical guest throughput data may show that, on average at 1 p.m., the attraction  112  has a guest throughput of 240 guests per hour and a guest throughput at 2:00 p.m. of 220 guests per hour, both with two rides open. The current conditions, as determined by the monitoring device  466 , indicate that the current guest throughput of the ride at 1 p.m. is 120 guests per hour with one ride  118   a  open. However, ride schedule data provided to the virtual queue controller  430  indicate that a second ride  118   b  is scheduled to open at 1:30 p.m. First, the virtual queue controller may determine that the historical guest throughput for one ride vehicle at 1:00 p.m. is 120 guests per hour, and that the ride throughput per vehicle is on par with historical guest throughput data. However, the historical guest throughput data shows a trend indicating that at 2:00 p.m., guest throughput for one ride vehicle historically decreases to 110 guests per hour. The virtual queue controller  430  may be configured to consider the decreasing guest throughput in calculating wait times. Additionally, although the current guest throughput is only 120 guests per hour, the virtual queue controller is configured to increase the expected guest throughput by a factor of two at 1:30 p.m. to account for the opening of the second ride vehicle. The expected ride throughput should increase to 240 guests per hour minus the anticipated decrease in guest throughput. Thus, the expected ride throughput at 1:30 p.m. may be 230 guests per hour. Using the estimated guest throughput data and current queue conditions in relation to the guest position, the virtual queue controller may dynamically determine wait times  582 . Additionally, in certain embodiments, the virtual queue controller may continually calculate the variable guest throughput to account for changes in current guest throughput and other queue conditions, in order to provide guests with updated wait times. 
     In some embodiments, the virtual queue controller  430  further utilizes other queue conditions to determine wait times  582 . Specifically, the virtual queue controller  430  may be configured to consider various factors, such as, but not limited to, previous guest behavior, guests&#39; current activities within and outside of the queue, current location or historical locations of the guest within the park, weather, calendar information (e.g., time of day, day of week, holidays, etc.), demographic information, number of guests within a group(s), and so forth. Further, in certain embodiments, the virtual queue controller  430  may record real-time queue conditions as historical queue condition information for future use. For example, acquired real-time queue conditions may indicate that one ride  118   a  has historically slower guest throughput relative to the other rides  118   b ,  118   c , even if all three rides  118  are otherwise alike or of a same type. Such slower throughput may be because an entrance in the loading area for the ride  118   a  is farther from the entrances of the other rides  118   b ,  118   c , because a loading angle involves slower loading, or because show props adjacent the ride  118   a  cause guests to linger at the ride entrance. Accordingly, a more accurate estimated guest wait time may take into account which of the rides  118  is closed and use historical guest throughput information associated with each individual ride  118 . For example, when the slower ride  118   a  is closed, the estimated guest wait time may use historical guest throughput for the faster rides  118   b ,  118   c  and not from the closed slower ride  118   a  in calculating an estimated guest wait time. 
     In certain embodiments, the virtual queue controller  430  may be configured to determine the wait times  582  for each attraction  112  based on a coordinated analysis of other queue conditions. For example, in certain embodiments, the virtual queue controller  430  may receive ride schedule data and guest throughput data for a plurality of attractions  112 , and may be configured to coordinate the wait times  582  for the attractions  112  based on the received data. In certain embodiments, the virtual queue controller  430  may utilize other types of data to perform a coordination analysis. For example, the virtual queue controller may receive crowd flow data and/or wait times for other rides, and may utilize this data to provide accurate wait times  582  for each attraction  112 .
