I really like the Calorie Commando on Food network. If you want to have some traditional foods healthied up a bit, he does it.
I also tend to try to make food a little healthier when I make it. Depending on when you go (soon?), you could go for lighter summer type fare or what not.
Personally, my favorite is grilled meat. Carne Asada or grilled chicken (sans bbq sauce).
I live on the East Coast now although I am originally from the West Coast. I mentioned to someone that I've never been to Orlando (my company has a huge presence in Orlando), they were surprised only because it is where the east coast theme parks happen to be. I basically said "uhh hello! Disneyland is the place to be, not Disneyworld". Anyway, have fun
