I would with some of the buffets, the character will keep the little ones entertained, some of our favorites are Cape May Clambake @ Beach Club, characters for breakfast not dinner, they can also draw on the paperlined tablecloths, to this day it keeps my kids busy and they are 11 and 12.
Tusker House is a great breakfast buffet. My kids favorite.
Cinderellas Gala feast @ Grand Floridian great character interaction both breakfast and dinner.
This year Rainforest and Trex have been added to the dining plan, which if they have never seen, they both are very cool inside.
