Hi Natalie,
It sure sounds as though you have a wonderful trip coming up and by planning in advance, you are definitely ensuring that you will get the most out of your stay.
The official 2017 Disney Dining Plan brochure hasn't been released as of yet (here is the link to the
2016 Disney Dining Plan brochure for your reference) but according to the information detailed within the
2017 Free Dine Packages, which are now available to book via the Deals section of the Walt Disney Travel Company website here in the UK, the
Disney Dining Plan will include the following per person per night stay in 2017:-
1 x Self Service meal
1 x Waiter Service meal
2 x selected Snacks
1 x Refillable Resort Mug per stay
So, in essence, it appears as though an extra snack will be available each day.
Cinderella's Royal Table sounds like the perfect place for you to celebrate your daughters 6th birthday. You will need to be prepared in order to secure an Advance Dining Reservation for that particular day as this restaurant is one of the most popular places to dine at the Walt Disney World Resort.
As I am running out of room, please refer to
THIS question which I answered previously regarding when and how you need to go about making your reservation.
Wishing you a magical holiday filled with memories which will last a lifetime!
Emma
