Jambo, Rosa!
Thanks for stopping by the Disney Parks Moms Panel with your question. I'm more than happy to help!
If you are looking to change your reservation for dinner at
Boma - Flavors of Africa, the online system should give you the option to cancel your existing reservation when you select the new time. If for some reason it won't allow you to do that, there are two options for you. First, you could go to your dining reservations on
My Disney Experience and simply cancel the reservation for 5:20. Then you should be able to go in and make the new reservation. Second, you could call and let a reservation specialist make the change for you. These calls are usually pretty quick and easy and shouldn't take too long. If you decide that you want to try this option, the number is 407-WDW-DINE (407-939-3463).
I hope this helps so you can get the reservation you prefer, and I hope you enjoy dining at Boma. You absolutely must try the zebra domes and eat one (or two) for me!
Happy planning!
