Hi Jerusha! Welcome to the Disney Parks Moms Panel.
Cinderella’s Royal Table at Magic Kingdom Park has always been such a magical experience for us! My kids feel like true royalty as they climb the spiral staircase to the dining room. The inside is beautiful and the stained-glass windows are breathtaking especially on a sunny day. We have always found the food to be very delicious as well. Young Princesses and Princes are encouraged to dress up for the occasion.
I would start by searching for a time for your entire party of 11. If you really do not have a preference as to which meal you would like to dine at, then I would say search for each meal of the day! If you are unable to get a reservation for a party of that size, I would then say to try to see if splitting your party opens up more options for you. If you are able to get a reservation with a split party, I would make it a point to speak to the cast member at the reservation check in booth and just alert them that you all are together and were hoping to be seated near each other. There obviously isn’t a guarantee that you would be right next to each other, but I have often found that a lot of the cast members try really hard to accommodate guests!
I also recommend making your dining reservation as soon as possible. Dining reservations can be made 180 days in advance of your trip.
I hope that you are able to all dine together like royalty! Have a magical time!
