Hi Peter! Thank you for your question and for visiting the Disney Parks Moms Panel.
Be Our Guest Restaurant at Magic Kingdom is a fantastic choice for your party of 10. Last year my wife and I took our little girl and we were seated in The Grand Ballroom where you’ll see high, domed ceiling, chandeliers and snow-laced Gothic arches. It was absolutely stunning!
On a previous trip, we did something very similar to you all as we made several reservations for our large party. While we did end up being seated in two different locations I will say that the Cast Members worked really hard to seat us together. In fact, they ended up getting us really close to the rest of the members so it worked out great.
Upon check-in for your reservation, be sure to ask the Cast Members upon entering
Be Our Guest Restaurant as I’m certain that they will do everything that they can do to seat everyone together.
If you have any other questions, please let us know. Have a magical day and tell Mickey I said hello!
Bryan
