Hi, Ellen!
Welcome to the Disney Parks Moms Panel. Thank you so much for sending us your great question regarding Disney's FastPass+ program! FastPass+ is the ultimate vacationing planning tool for allowing you to reserve your place in line at some of Walt Disney World® Resort's top attractions.
But... things happen sometimes; plans can change, parks may close due to capacity, all kinds of things! That's where the
My Disney Experience Mobile App for your smartphone comes in handy. With the app, you can modify or cancel any FastPass+ reservations on-the-go at any point in your vacation - should you arrive at a theme park temporarily closed for capacity, you can use the app to cancel your selections, or just allow the time to expire. Nothing happens to any unused FastPass+ selections, the time will just "expire" and you'll be able to make additional selections after that. However, if you choose to login to the app and modify or cancel, you will be able to make new selections immediately based on attraction availability at the time.
I hope this answers your question, Ellen. Please let me know if you should need any additional assistance planning your magical vacation. It's the most wondEARful time of the year at Walt Disney World® Resort!
