Hi Mary!
Character Dining at Walt Disney World does book up in advance, however you still may be able to get some reservations for your stay. I'd recommend that you visit
Disney Dining Online to search for some reservations just as soon as you can!
A few of the
best locations that include
Goofy, where you may have some luck getting a reservation include:
Cape May Cafe for breakfast on your Epcot or Hollywood Studios day
Tusker House for breakfast or lunch on your Animal Kingdom day
If you have no luck today, check back again this evening, and again tomorrow. There are always changes in availability so check often.
Thanks for visiting the Moms Panel. I hope you'll visit me again soon if I can be of further assistance to you as your finalize your plans!
Wishing you a simply Magical time at Walt Disney World with your family Mary!
