Hi Sabrina, and welcome to planDisney!
Plans change, but it is good to know that
Walt Disney World Resort is accommodating and understand that change happens.
As you know, theme park reservations using the
Disney Park Pass Reservation System are required for each day you plan to visit. If for some reason, you need to make any modifications to your current theme park reservation, you can do so. Modifications can include different dates, theme parks, or guests. You can change the date to any date you wish as long as availability exists. Please note that "you can make changes to your tickets, prior to midnight ET of the day before your ticket’s first valid use date." Also, if the new date yields a higher price, you will have to pay any additional costs associated with that change.
We will be here to answer any additional questions you may have; just let us know how we can help.
Have a magical time!
Raquel
