Hello, Tricia!
Absolutely!
You are going to love the
Disney Deluxe Dining Plan AND love the ambiance, entertainment and dining selections at Cinderella's Royal Table. Get ready for a spectacular evening!
Click on the link above for a pdf copy of the Deluxe Dining Plan; scroll down to page 4 in order to see that CRT is, in fact, on the list. More importantly, you'll see that almost all of the restaurants that are in a WDW park, Disney-owned and operated resort and Downtown Disney participate in the Dining Plans. (That is subject to change from year to year, but has been the norm for several years now.)
Enjoy your trip, your dinner at Cinderella's Royal Table and your Deluxe Dining Plan, Tricia! You're in a a trip filled with treats!
Send more questions as you think of them, too. I love to help!
