Hi Patricia!
What a wonderful, magical experience your group is going to have at
Walt Disney World! I believe you will find the resort and parks to be quite accommodating, Mickey Mouse a great guy, and Tinker Bell will leave you breathless when she flies from the castle spires before the fireworks brighten the night sky.
For such a large group, I suggest you call Group Reservations at (407) 939-1942. Cast Members here assist groups needing ten or more rooms, so they can tell you if you qualify for a discount and help you reserve a block of rooms.
Some members of your crowd may have a disability that makes tolerating waits in line a no go. If so, the
Disability Access Service (DAS) can make for a much more pleasant theme park experience. Currently you need to register in person at a park's Guest Services, but by the time of your visit the process should be available through a video call. The DAS recipient will be given a return time to enter an attraction that allows him to skip the queue. You may contact Disability Services at (407) 560-2547 or at disability.services@disneyparks.com.
Wishing you all a wonderful adventure when you visit the mouse!
Elisabeth
