Wilderness Lodge, although, as has been mentioned above, the design is very similar.
Wilderness Lodge has more water, a lot more water, with a variety of boats to rent.
It's just a boat ride away from the Magic Kingdom.
The Electric Water Pageant comes by for a visit.
The theming is extraordinary.
having said all that, AKL does offer more animals and more exotic restaurants. (this may or may not be a good thing, depending on your tastes.)
