The Basic Dining plan is 1 counter service, 1 table service and 1 snack credit. This includes a dessert and no appetizer. The cost is $38/person.
The Deluxe Dining plan is either 3 table service or 3 counter service and 2 snacks. Each includes an appetizer and dessert. The cost is $69/person.
I would recommend doing the deluxe if you're interested in either the signiture dining or the dinner shows. Each will be 2 TS credits.
