Hi Kathy! It sounds like you are getting ready for a visit fit for royalty at the Walt Disney World Resort! I am happy to share that all of your vacation wishes can come true!
Enjoying Disney Dining inside Cinderella Castle is possible at
Cinderella’s Royal Table! This fairytale dining experience is available for breakfast, lunch, and dinner! Not only will your taste buds receive royal treatment, but so will you! The Disney Princesses serve as greeters throughout your dining experience! This is an extremely popular dining experience in Magic Kingdom Park! You can make Disney Dining reservations 60-days prior to your vacation arrival date! I strongly recommend that you mark your “60-days prior date” on your calendar and get on to your My Disney Experience account around 5:45 AM to try making your reservation!
Take your Walt Disney World Resort vacation to the next level! In fact, take it to the level underneath Magic Kingdom Park! The tour you are describing in your question is known as
Disney’s Keys to the Kingdom Tour! This truly amazing experience is a 5-hour walking tour that will span the history of Magic Kingdom Park and Walt Disney! Included with the admission of your tour is a delicious lunch, an exclusive gift, as well as a look at the underground “utilidor” tunnels that Cast Members use to travel under Magic Kingdom Park! This experience can be booked directly on the Walt Disney World Resort website. Once you arrive at the Disney's Keys to the Kingdom Tour webpage (linked above), you will click "Check Availability" and follow the prompts.
Wow, Kathy! Just these two experiences alone are going to make for a magical visit! I hope you have an amazing vacation!
Happy Planning!
Jonathan
