The restaurant at Fort Wilderness is good. Last time we were there was October 2011. They have a chicken takeout dinner that is excellent, and a lot of food. Great for bringing back to the campsite.
Hoop-de-do-review, at Fort Wilderness, is definitely worth getting reservations for! It is a lot of fun.
The carriage ride at the campground is surprisingly good, especially in the evening. I know the "haunted" carriage ride in October is fun for kids, I don't know about other times of the year. A little expensive, but everything is.
As posted earlier, feel free to keep asking questions!
