Hi, Claire! Welcome to planDisney!
Adding even more magical days to your Walt Disney World Resort vacation is always a great idea. There's so much to see and do, it just makes sense to give yourself more time to experience as much as you can! Let's get you ready to make the most of all of your Disney days.
Since you haven't used your ticket yet, you may be able to add the extra day right in your
My Disney Experience account. Just sign in to your account on the
Walt Disney World homepage, then click on the "My Disney Experience" logo in the menu bar. On the next page, scroll down to "My Plans, Reservations and Tickets," and click on "Tickets & Memory Maker." If your ticket can be modified online, you'll see an option to do so right next to the entry for your ticket. Follow the prompts to add your extra day, and you should be good to go!
If you find you can't add your extra day online, I'd go ahead and
call Guest Relations at the number listed under "Existing Tickets." A friendly Cast Member will help you get everything squared away.
Next, to change the dates for your
Disney Park Pass reservation, you'll actually need to cancel your existing reservation and make a new one. I just took a look at the
Availability Calendar for June 25 and the days following, and the only theme park with reservations available at the moment is EPCOT. If you happen to have reservations for any of the other parks during that time, I'd try to hold onto them if at all possible. I'd hate for you to cancel them and not be able to get the park you wanted. Just be sure to check that calendar before you cancel the ones you have!
I hope this helps you plan your Walt Disney World adventure, Claire. Please come see us again if you have any more questions!
Keep Disney Dreaming,
Kathy K.
