Hey there, John!
The only thing better than a
4-day ticket to Walt Disney World Resort is a 5-day ticket, of course!
John as long as your theme park ticket is within 14 days of first use, not expired, and still has at least one day remaining on it you will be able to add an extra day. Additionally, a few tickets, such as special Florida resident discount tickets may not be able to be modified.
You can easily modify your ticket through your
My Disney Experience Account. After you log in, go to "My Plans." Halfway down the page, you should see a blue tab that says "Tickets & Memory Maker." Beneath each assigned ticket in your account, you will see a blue "Change Ticket" button that will allow you to modify days, or add the Park Hopper Option.
Don't forget to make your
Disney Park Pass system reservation for your extra day, John!
Have a magical stay!
