Hey there, Heather!
Welcome to the Disney Parks Moms Panel!
Modifying an Advanced Dining Reservation has become magically simple since the latest My Disney Experience upgrade.
Just log into your
My Disney Experience account, either online or your mobile app, click on "My Reservations" and select the Crystal Palace reservation. Once there, you can click on "Modify" when using the mobile app or "Update Guests" if using the online version. If there is availability,it will be displayed and you can then select and update your reservation!
If you find yourself having a bit of trouble with My Disney Experience, just call 407-939-1947.
I hope this helps to make your dining experience even more magical!
If you have more questions, please visit with us again soon!
Happy dining!
