Hi, Kerrie! Welcome back to the Disney Parks Moms Panel.
By staying at Disney's Art of Animation Resort you are absolutely able to start making your FastPass+ selections 60 days prior to your check in date. All you need to do is log into your My Disney Experience account connected to your hotel reservation and be sure all Theme Park tickets are linked to your account.
You may pick three selections each day for each person in your party at one Theme Park per day. For example you may make three selections for Magic Kingdom on Monday, three selections at Epcot on Tuesday, etc. Once you have enjoyed those three attractions, you may book one additional FastPass+ by visiting a FastPass+ Kiosk in the same Theme Park as the attraction you wish to make a selection for. Once you have finished that attraction, you may visit the Kiosk for another selection.
It is a good idea before your 60 day mark to plan out what Theme Parks you would like to visit each day of your vacation and what attractions you would like to make FastPass+ selections for. Write down a couple alternate attractions if one of your top three attractions do not have any FastPass+ selections available. Disney's Hollywood Studios and Epcot use a tiered FastPass+ system, so be sure to plan accordingly.
Please stop by the Disney Parks Moms Panel if you have any additional questions about FastPass+ or anything else while planning your magical Walt Disney World Resort vacation.
