It’s easy to cancel a dining reservation on the My Disney Experience AppWhen you make a dining reservation, a credit card will be required to hold your spot. If you can’t make it, make sure you cancel at least 24 hours in advance. Otherwise, your card will be charged a flat fee for each person on the reservation. You can cancel on the My Disney Experience App, online, or by calling 407-WDW-DINE (407-939-3463).
