Hi Tiffany,
It's so great to hear that you have your own Fab Five just like Mickey, Minnie, Donald, Goofy, and Pluto! Though I'm sorry to hear that one of your Fab Five can't make it to join you in all the magic of the
Disneyland Resort.
While the theme park tickets you purchased are
nonrefundable, you are able to cancel a theme park reservation that you made.
Theme park reservations can't be modified, but they can be canceled.
If you sign in to your Disney account and go to your
My Theme Park Reservations page, you should see a display of your theme park reservations. When you click on your reservation and look at the details, you should see an option to cancel the reservation. You'll see that you can select the names of the Guests in your party for whom you want to cancel the reservation. In your case, you should be able to cancel the theme park reservation for only the one Guest who is not able to join you.
Tiffany, I do hope this helps give you the information you need to update your theme park reservations. If you need additional assistance with your tickets, you can
reach out to the Disneyland Resort Ticket Services team by calling them at (714) 781-4636.
Here's wishing you a wonderful and magical visit to the Disneyland Resort!
Jerry
