Hi Brian! Welcome to planDisney!
Thanks for sending us your question! From your arrival date, it looks like you may be visiting soon, then again in December. If so, what a fun few months you have ahead of you! Both months are great times of year to visit (when isn't a good time for a Walt Disney World Resort vacation, really?) with all of the
holiday celebrations taking place!
The easiest way to change
Walt Disney World theme park tickets is through the
My Disney Experience mobile app. Log in to your
My Disney Experience account on the app. Touch the three lines in the bottom right-hand corner, then select "Tickets and Passes." If you haven't already linked your daughters' ticket to My Disney Experience, you can do that on this page. If you have, scroll through to find the ticket you want to change and you will see the option to change the ticket. This should walk you through the process to change the ticket.
If you are unable to make the changes you want on the app, you can
give Disney a call at (407) 939-7679 and speak with a Cast Member about changing the tickets. They will be happy to assist you!
I hope this helps, Brian! Please let us know if you have any other questions.
