It's good to see you back, Melanie Elizabeth!
It sounds like you are in a little bit of a tight spot, not knowing if you will be able to join us here at
Walt Disney World Resort this September. When in doubt, I agree with you that it is best to go ahead and snag your
Disney Park Pass system reservations. Melanie Elizabeth, while you can not technically modify your park selections to another day, you can go ahead and cancel previously reserved dates with no penalty. Once your Disney Park Pass reservations have been canceled, you may then go ahead and make theme park reservations for your new holiday, pending availability.
Melanie Elizabeth, have you seen the
Disney Park Pass system availability calendar? It looks as if all of the dates for your potential rescheduled trip are still available, so you may want to keep your eye on that.
I hope that this helped, Melanie Elizabeth. We love to see you, so please come back here to the Disney Parks Moms Panel if we can help as you plan your magical holiday!
See you real soon!
Sarah B.
