My wife retired from WDW, and we still go to Fort Wilderness a few times a year. It is a really nice campground and the restaurant on site (Trails End) has a great breakfast and dinner buffet. If you like a dinner show, Hoop de do Revue is good, but we found it rushed. The bigger sites are the premium sites, which cost a bit more (not too much). No matter what type of site you get, it isn't cheap compared to many other campgrounds. But it is good. They do have a free campfire and sing along with Chip and Dale which is followed by a movie each night. The two pools are nice, the Meadows pool is the bigger one more geared to families and the Swimming Hole pool is the quiet pool. There is boat transportation to the Magic Kingdom and bus transportation around the campground and to the other parks and facilities. You don't need to bring another vehicle unless you want to.
If you can't get a reservation, there are several campgrounds in the area. Lake Louisa State Park has a nice campground in Clermont that is about 40 minutes away.
