International Drive leading right to the Beltz outlet malls has every restaurant you could think of. There is a Shoneys or Big Boy or something like that that has a breakfast buffet. To find more of that stuff, pick up those brochures at gas stations, the outlet mall,etc. They will have ads and coupons. The down side is time away from the parks while you are driving to and from somewhere outside the parks. Traffic can be horrific and will take up even more precious time.

The Trail's End Buffet over at Fort Wilderness (campground) has buffet meals that are the bargain of the property. You may want to check them out for a breakfast or dinner.
