Typically, an 18 hole round will take an hour per player. For a foursome, we recommend renting the simulator for four hours. If your time runs out in the middle of your round, you may rent the simulator for an extended period of time if no one is scheduled to use the bay after you. However if someone is scheduled to use the bay after you, you must finish 5 mins prior to your end time no matter where you are in your round.
