Welcome to planDisney, Bethel! We are glad you brought your question to us.
At this time, all Guests ages 3 and up require a
Disney Park Pass theme park reservation in addition to valid admission in order to enter a theme park. I know it can be a bit tricky when adding an additional Guest to your plans. You may want to check periodically and see if you can make a Disney Park Pass reservation for your grandma for
Magic Kingdom Park on Friday. Other Guests' plans change all the time, and it is possible that you might be able to nab a reservation for her. If you are not successful, then yes, if Disney Park Pass reservations are available for Magic Kingdom Park on Saturday, you can modify your reservation and switch your group from Friday to Saturday.
To change the date of your Disney Park Pass reservation in the
My Disney Experience mobile app, use the menu button in the lower right corner to select "Future Plans" and click on the Disney Park Pass you need to change. You should then see the option to modify and can select a new date and park. Depending on what ticket type you are using, you may first need to change the start date of your ticket. Use the menu button to go to "Tickets and Passes" and look for the option to "Change Ticket". To modify Disney Park Pass reservations on the
My Disney Experience website, go to "My Plans" and select "Manage Reservation", then "Modify Reservation" and follow the steps.
Bethel, I hope you're able to make a Disney Park Pass reservation for your grandma and you can all enjoy
The World's Most Magical Celebration together! If you have any additional questions, please feel free to stop by and see us again anytime. We are always happy to help.
