Hi Brian! Welcome to the Disney Parks Moms Panel!
You are smart in planning ahead for your summer vacation to the Walt Disney World Resort! I like to plan out my
FastPass+ selections in advance, so when it is my time to schedule them, I know exactly what I want. I also like to plan my FastPass+ for earlier in the day, because when my initial three FastPass+ are used, I can add more, one at a time (subject to availability). These additional selections can be made on a FastPass+ kiosk in the theme parks, but an even easier and more convenient way to do this is to download the
My Disney Experience mobile app prior to your trip.
You are correct that there are tier systems in Epcot,
Disney's Animal Kingdom and Disney's Hollywood Studios. And the good news - you can choose three Tier 2 FastPass+ should you decide not to use a Tier 1 selection. You would be all set to go with the three attraction choices you have in mind!
Enjoy planning your trip, Brian! Please visit us again with any other questions you may have!
