Hi, Danielle! I am glad to hear you have made your Advance Dining Reservations! This is a great way to make sure you get the most out of the Dining Plan.
Gratuities are not included, so plan to tip between 15% - 20% based on the quality of service you receive. Cast members at the restaurants are typically very good and work very hard to give you the very best service and to earn their gratuities. If you have 6 or more guests in your party, an automatic 18% gratuity will be added to your bill. Tips can be paid in cash, credit card, or charged to your Key to the World card.
There are exceptions. For the following dining experiences, gratuities are included: Cinderella's Royal Table, Mickey's Backyard BBQ, Spirit of Aloha, and the Hoop Dee Do Revue. For a complete list of restaurants, click

Enjoy your 10 day vacation to WDW!
