Hi Marlene!
There are two character meals that I think would be good for him. My boys LOVE
Chef Mickey's breakfast buffet. It is good food with the traditional characters he will probably recognize. (Mickey, Minnie, Pluto, Goofy) This is located at the Contemporary Resort which is close to you and the Magic Kingdom.
Another good choice, if he is a Winnie the Pooh fan, is
The Crystal Palace. It's located inside of Magic Kingdom and is also a great buffet where you eat alongside Winnie the Pooh and all his friends.
I hope one of these will work for you. You can see all of the
character dining meals on the Disney World website.
Please let me know if you have any other questions!
