I would try for Park Fair 1900 at the GF it is Cinderella, the Prince & Step mother & Sisters for dinner. We also enjoy Ohana for Breakfast. Crystal Palace at MK with Pooh & Friends is good for any of the meals we like lunch nice break during the day before the Parade. My kids at that age also did really well eat around the World Showcase in Epcot at alot of the Counter Service places, they were better about trying new things at that age.
