3) FastPass+ and Dining Reservation Times
There is a lot that you will need to remember while you are at Walt Disney World. You don't want to have to be constantly trying to remember what time you're supposed to ride Frozen Ever After and when your Coral Reef Restaurant reservation is. Screenshot your reservation times on your phone so that they will be easy to find. Make sure that everyone in your party has a copy of the times, especially if you plan to go off in different directions. You can also write the times down the old fashioned way with pen and paper, and then give everyone a copy. While it's true that you can check the My Disney Experience App to see your times, WiFi is sometimes spotty in the Disney Parks. The app also has a reputation for going down from time to time. You don't want to miss your dining reservation (and be charged $10 per person) because there was a problem with the app. If you have everything that you need to know elsewhere, you won't have a problem if the app won't load.
