Hey Alicia!
Welcome to the Disney Parks Mom Panel!
Cinderella's Royal Table is a dining experience not to be missed at Walt Disney World. Advance payment cover the entire cost of your meal in full. You will not be required to pay anything additional as this already includes tax and 18% gratuity. However, if you receive the exceptional services which Disney is known for you can always add more to the gratuity after your meal.
The princesses in attendance at Cinderella's Royal Table are always subject to change. However, you should expect Cinderella herself to be greeting her royal subjects and taking pictures in the Lobby. You might also see Aurora, Snow White, Jasmine, Belle and Ariel during the meal. I have also heard on different occasions that Prince Charming might even show up for the feast.
I hope this helps your planning. If you have any other questions please come back and see me.
Wishing you a magical Disney vacation and a pixie-dusted day!
