2. You have access to FastPass+ no matter what
Whether you buy a 1-day ticket or a multi-day ticket, you will have the ability to book FastPass+ options before you get to the park—but you can wait and make FastPass+ selections in the park as well. Using the My Disney Experience app, you are able to select up to three FastPass+ attractions for one park per day. Once you finish your initial three, you can then select one attraction at a time and even choose one in a different park if you plan on park hopping.
