Hi, Amber!
I hope you write a trip report - I don't think I've ever read one that involved camping at Fort Wilderness! I am not much of a camper (heck, I'm not a camper at all!), but I could probably handle staying in that beautiful camper that you're renting!
As I always tend to have opinions about food, I'll give you my two (or twelve!
) cents:
My FAVORITES on your list include:
BOG Dinner - We LOVED this meal last time! I don't know why some people don't like it, as I found both the surroundings and the food to be very good!
Crystal Palace breakfast - This is my favorite pre-park opening breakfast. I highly recommend Pooh's Puffed French Toast and the make-your-own omelet station!
Liberty Tree Tavern lunch - This is one of our favorite lunches! The food is great, but we ADORE the Ooey Gooey Toffee Cake! Yum!
I've not yet been to Sanaa or the 1900 Park Fare dinner, but both are on the itinerary for my next trip! I always here such good things about both of them so I'm sure they're great!
I didn't love the 'Ohana breakfast, but that was mostly due to the character interactions, not the food. The Liliko'i Juice is fabulous and I really liked the bread basket and the fresh fruit. My favorite breakfast at the Poly is at Kona, but I understand your desire to eat here due to the kiddos and your love for Lilo.
I've never been to House of Blues, but I believe people like it. If you're looking for Southern food, Boatwrights at Port Orleans Riverside is often described as a surprise gem of a restaurant. If you're choosing it due to location, I'd also highly recommend Wolfgang Puck Express (the Marketplace location is best due to their expanded menu). This is one of the best QS places on Disney property!
I've also not been to Chefs de France or Tutto Italia. I actually really loved La Hacienda de San Angel - that was a surprise favorite last time. If you're interested in Italian I'd highly, highly recommend Via Napoli - their pizza is excellent and they also have some very tasty pasta. Via is my favorite restaurant in all of Disney World.
Good luck on your dining choices!
