Definitely a character meal or two. She should examine which one might fit their needs best both from characters present and food and manner of service. CRT and Akerhaus are princess selection. 1900 Park Fare has Cinderella and the dinner has the stepsisters. I'm eying Tusker House (Donald) as there have been good reviews for that as well as Crystal Palace (Pooh). But you will find other fans of things like Garden Grill, which I believe is served family style, and there is a Disney junior one but seeing these little characters huge with giant heads does freak some kids out. And Chef Mickey's of course. And I'm not even covering them all. So I'd search out and figure out what might work best.
For non-character meals, I think I'd go with food that can be kid-friendly in an interesting atmosphere. I wonder about Via Napoli -- pizza, pasta and giant fun pizza ovens. Coral Reef is another one that could be fun given the huge aquarium. Prime Time Café has TVs at some tables showing old 50s shows which could be entertaining for the kids. And there is Casey's with some hotdogs and corn dog nuggets which might be welcome by the kids. That's just what I've identified off the top of my head from my own research. I'm sure others can offer up ideas of some other fun ones. Hope they have a great time!
