Hello Carla, welcome to the Disney Parks Mom's Panel!
Character Dining is a big part of my family's Walt Disney World vacations. Reservations for large groups can be book at any Disney restaurant, including character experiences, but it should be booked at the 180 day window. I always try to book all my table service meals 180 days prior to my arrival, to make sure that we find availability at all our favorite restaurants and at hour preferred time.
Advance dining reservation can be booked online or by calling (407) 939-3463.
Large groups are not guaranteed to be sited together, even with a reservation. To better your chances arrive 15 to 20 minutes early.
Character experiences are great for celebrating birthdays and you can even
buy a regular cake or order and customize your own cake.
Do not forget to use the Birthday Recognition Button.
My favorite character dining experiences are Akershus Royal Banquet Hall, The Crystal Palace, 'Ohana and Tusker House Restaurant.
Thank you for visiting and letting us help you plan a magical celebration at Walt Disney World.
Miguel
