Hey Howdy Hey Tillie and welcome to planDisney fellow Buckeye!
Tillie, you are in for a super Magical treat with a dining experience at
Cinderella's Royal Table in Magic Kingdom. The only thing better than visiting Magic Kingdom is sharing a meal with Royalty inside Cinderella Castle! I am so excited for you to have this experience. It is sad to hear that you will be one less for your reservation and YES you still have time to modify your reservation, so let's run through the steps on how to do so.
As you have experienced, Cinderella's Royal Table is one of the
Signature Dining experiences in Walt Disney World Resort that you have to pay for upfront when making your reservation. With that being said, the only way to modify your reservation is by
calling Disney (407) 824-1391 and a Cast Member will be able to help you through this process.
I would also be sure to review the cancellation policy in the email confirmation you should have received after booking your reservation. Signature Dining locations, such as Cinderella's Royal Table, do have a more specific time frame for canceling reservations compared to other locations. Most often with Signature Dining, you must cancel your reservation 48 hours before your reservation to get a full refund. Make sure to review this policy in your email so you know what to expect before calling Disney.
I hope this information was helpful and I wish for a Magical vacation for you and your party on your upcoming trip. Please feel free to reach out if you have any further questions, we would be happy to help!
Have a Magical Day,
Nick
