Goofy's is usually a little noisier than Storytellers. Goofy's has always been a family favorite. They offer a very large buffet to chose from, fun games for the kids to play through-out their meals & on average about 5-7 characters. We always see Chef Goofy & Pluto, then have seen as well: Chip, Dale, Baloo, Brer Fox, Minnie, Alice, Aladdin & Jasmine.
Storytellers is a quieter meal with a game of follow the leader for the kids. The characters are the animal variety: We saw Turk, Meeko, Kenai, Chip, Dale & Brer Fox. The buffet is smaller than Goofy's or you can order off the menu. Keep in the mind the menu prices will be high since you're still playing for the "character experience".
We did the Surf's Up with Mickey & really liked it. This is also a smaller buffet, but they had different types of food that we hadn't seen at the other character meals. This is the only meal Mickey is at! They hula-hoop, surf, dance, etc during this meal. My kids loved this one. They saw in addition to Mickey: Pluto, Goofy, Minnie & Stitch.
You also could look at the Minnie & Friends breakfast at the Plaza Inn. Your child's age tells me that characters like Pooh, Tigger & Eeyore might be nice. Minnie's is a buffet that we've seen anywhere from 7-14 characters at. These are more of the "classic" characters. In addition to Minnie as the host & the Winnie the Pooh characters, we've also seen: Chip, Dale, Peter Pan, Hook, Mary Poppins, Alice, Rafiki & Honest John.
Of course there's always Ariel's Grotto with the princesses. The food is served family style & has always been very good. You see Ariel when you come down the stairs & then will see 4 more princesses during your meal. They formally announce them.....lots of fun for princess lovers!!
Good luck picking & have fun!!
