Hey there, Lana!
Welcome to planDisney. Thank you for sending us your wondEARful question about
Disney Park Pass theme park reservations.
Lana, you are not stuck with your original Disney Park Pass theme park reservations. If the
theme park reservation availability calendar shows the date you want to switch to as available, you can cancel your original theme park reservation and make a new one! Because you have a 5-day window of use, your three theme park reservations can be scheduled for any of those 5-days, even if that means making a last-minute adjustment.
However, please keep in mind that theme park reservations are limited and subject to availability. Your 5-day window does not guarantee that the theme parks of your choice will be available all 5 days. I hope this makes sense, Lana! The good news is that I find theme park reservations available for almost all of my last-minute plans. I live locally and enjoy many “spur of the moment” visits.
Lana, if you have any additional questions, please visit planDisney again. We are always hEAR to help you!
Wishing you a Magical Vacation,
Priscila
