This is exactly what you get (as quoted by my TA to me when I inquired):
The Dining Options allows you to eat at over 100 participating Disney restaurants with a full range of dining experiences at substantial savings:
~ 1 table-service meal including appetizer, entree, dessert, non-alcoholic beverage and gratuity
~ 1 counter-service meal including entree, dessert and non-alcoholic beverage
~ 1 snack including either a frozen ice cream bar, popcorn scoop, 20 oz bottle of Coke, Diet Coke, Sprite, Dasani Water or a medium fountain soft drink
~ You may also exchange 2 table-service meals for 1 Signature Dining Experience like the Spirit of Aloha Show at Polynesian Resort.
It is $35 per adult per night and $10 per child (3-9) per night.
If you stay 5 nights, you get 5 table service meals, 5 counter service meals and 5 snacks... you can use it all up in 2 days if you wish!
