When booking through Disney online or through their My
Disney Experience App,
you will be able to make these Fastpass
reservations. If you are staying at a Disney World resort, you will be able to make these reservations 60 days prior
to check-in; if not, 30 days. Each
reservation will allow you to show up at that attraction within the 1 hour
window you’ve chosen, and ride with little wait. You can select 3 per person initially, and
after you use all 3, you can select 1 additional option 1 at a time. After you use that, you can get 1 more, etc.
