Just to clarify...there's no such thing as a "Fort Wilderness 1-bedroom villa".
Fort Wilderness has cabins and campsites only.
You can get a 1-bedroom at the Villas at Wilderness Lodge, which is part of the Wilderness Lodge resort, a completely separate resort from Fort Wilderness. It's also along Bay Lake, but I think it's about a mile down the walking path. FW and WL don't share any facilities.
I haven't stayed in a cabin, but the 1-bedroom villa has a master bedroom with king bed, a living room with a sofa bed, and a full kitchen, complete with pots, pans, glasses, dishes, etc. Full-size fridge, stove, dishwasher, microwave, coffee maker. Toaster, too, I think.
There's also a washer/dryer, and a jacuzzi tub. The bathroom/vanity area is immense. Oh, and 2 TV's. One in the living room, one in the bedroom.
