Goofy's Goofy's Goofy's! Ugh...it is so good. The food is great for kids & adults & there are a variety of characters. They have brunch & dinner. I go every year & can't have a b-day w/out it. Oh, & they don't do the pots & pans anymore to the Tarzan song. They do the Twist now.
Many eateries also have mini cakes that can come in a treasure chest. It also comes w/ a compass & some other small goodies. I'm just not sure if you'd want to spend money on that or not.
You can also try to find Alice & the Mad Hatter @ Coke Corner for musical chairs. I don't know what time they're there, but I'm sure your son will have fun.
