Hey there, Stephanie !
Thanks for visiting us here at planDisney! Are you counting down the days until your arrival at The Most Magical Place on Earth?
Magic Kingdom Park is one of my most favorite Walt Disney World Resort theme parks (though, honestly, they are each my most favorite in a way). I can imagine you're so looking forward to all the magic that awaits you.
I think Mickey will be super excited to hear you made your
theme park reservations using the Disney Park Pass system. I'm sure, though, that Mickey will be sad to hear that your mom will not be joining in all the fun this time around. My best suggestion to have the person who made the reservation or who is managing the reservations cancel the theme park reservation that your mom will no longer be needing.
You can cancel a theme park reservation in the "My Plans" area of your
My Disney Experience account online or in the "My Plans Ares" of your
My Disney Experience mobile app. If you're using My Disney Experience online, you can go to the "My Plans" area, look at the "Daily Itinerary" to see the theme park reservation, click the "View Details" button to see more information, and click the "Cancel this Reservation" link. If you're using your My Disney Experience mobile app, you can go to the "My Plans" area, look at the "Daily Itinerary" to see the theme park reservation, tap the reservation to see more information, and then tap the "Cancel" button.
While theme park tickets for Walt Disney World Resort are not refundable, they could be used for a future visit depending on their expiration date. My best suggestion is to give a call to Walt Disney World Resort Ticketing at (407) 566-4985 and give them the details of the ticket type and when it was purchased. The friendly ticketing team Cast Members can provide information on when the ticket expires, how it could be used for a future visit, or other options that could be available.
Stephanie, here's wishing you all a fun and wonderfully magical visit to Walt Disney World Resort!
Jerry
