Summarize this article:

Avoid paying high fees for tickets by buying your park passes in advance. You can use the Disney World website to check out the prices and select passes for the theme parks you are planning to visit. Disney ticket prices drop with every extra day to your visit you add, so try to buy all your passes at once. Passes can be very expensive when purchased through Disney's website, so you may want to consider buying your passes from an authorized third-party seller. You can do this through a third-party seller like Undercover Tourist. You can also look for discounts through your local auto club (Triple-A has discounts on these theme park tickets when you have an account with them), your student union, your human resources office at work, or through Veteran Affairs if you are in the military. Do not buy passes on sites like Craigslist, eBay, or other unauthorized online ticket brokers. You cannot use someone else's unused Disney tickets, as Disney will not accept tickets that are registered under someone else's name. You cannot take coolers into the parks, but you can take backpacks and purses. Load up your bag with supplies like sunscreen, toiletries, band-aids, refillable water bottles, and snacks. Food and supplies in the park are often expensive so avoid spending extra money on items you can bring with you. If you are a large party, you should each have a bag loaded with basic supplies, including non-perishable snacks and a refillable water bottle for every member who will be visiting the park that day. This will ensure that everyone in your party is prepared for a day of walking around outside and enjoying the park. A backpack is also useful for any leftovers you may have if you do decide to eat at a dining spot in the park. This way, you can snack on the leftovers later in the day. Beat the crowds by arriving at the park right at opening time. The beginning of the day is often less crowded and cooler than the afternoon, and this way, you can take advantage of all the park has to offer. This will also allow you to take a break in the middle of the day when the crowds and the heat are often at their worst and then return to the park in the evening. Most of the theme parks open at 9 am and have Extra Magic hours, where they stay open later in the evening as well. Getting to the park early can also help you get a better parking spot at your chosen theme park. Once you pay for parking for that day, you will be able to reuse that day to enter any other Disney World theme park at no additional charge for the day. One of the biggest hurdles during a visit to Disney World is the long lines for attractions and rides. You can download MyDisneyExperience or the Lines app to determine the wait time for each ride or attraction while you are at the park. You can then plan your visit around line times and avoid standing in long lines, which will eat up your chance to try other things at the park. The app works for iPhone, Android, and other smartphones. Preserve your Disney World experience by taking lots of photographs of the attractions, the shows, the rides, and of you posing with your favorite Disney characters. You can then save money by framing these photos and keeping them as souvenirs of your trip. There are photographers hired by Disney to help you capture your special moments at the park for which they can stick it on a card and you can print them out at home (or for an additional charge, you can have them printed out at the park). Make sure you are aware of the price of the photographs before you get have them printed.
Buy your park passes ahead of time. Bring your own snacks and supplies. Get to the park early. Use the MyDisneyExperience (by Disney) or the Lines (by Len Testa) apps to avoid long lines and crowds. Take lots of photographs and bring them home as souvenirs.
