Hi Tanya,
I am guessing that you have the regular Disney Dining Plan which includes one (1) Quick-Service Meal, one (1) Snack, and one (1) Table-Service Meal per person, per night of your package stay for everyone in the party ages 3 and over.
All of the Signature Dining, Dinner Shows, Private In-room Dining and Cinderella's Royal Table require (2) Table-Service meal entitlements per person.
These are all shown in the 2011 Disney Dining Plan brochure which you can find
HERE.
You are able to use your meals and snacks in any order throughout your package stay until your total is depleted so, if you would like to dine at one of these restaurants, I would recommend that you simply do not book a table-service meal for one of the other days of your stay.
Wishing you a magical trip!
