Hi Hallie!
Welcome to planDisney.
I'm very happy to see that you have a dining reservation at one of the most magical locations at Walt Disney World - inside Cinderella Castle at
Magic Kingdom Park! It doesn't get any better than that!
For any dining within a Disney theme park, you will need park admission tickets, even if you are only visiting for dining. If your reservation is for earlier than the official park opening time, you will see an entry point for guests with dining reservations, so you can enter the park before it opens. You will be admitted in plenty of time for your 9.10am reservation, and I suggest you arrive at the gate around 30 minutes prior to that.
Take the opportunity for some photos on Main Street U.S.A., and in front of the Castle before the park gets really busy. The Magic Kingdom is at its most beautiful first thing in the morning.,
Cinderella’s Royal Table is very popular for breakfast, lunch, and dinner. Located right inside Cinderella Castle you'll meet Cinderella before you go up to the dining room where Disney princesses will visit you during your meal.
Please come back and visit us again if you have any further questions, and you can
send me a direct question if you wish. We will be happy to help you plan your magical vacation to Walt Disney World.
Sue
