I'll break it down by park:
MGM - Sci Fi, 50's PT, or H&V for late character lunch
AK - Rainforest or head to Boma
Epcot - Garden Grill with characters
MK - Tony's for late character lunch, supper in the castle if you don't have CRT PS, LTT character dinner
Out of the parks there are fun options, but on our last night there's no way the kids want to leave the parks to eat. They want every last minute in the parks, and so do I!
