Top on our list are the animals.
1. The savannah with the animals
2. The theme/decor (although I still think WL has the best theme/decor)
Mike,
Interesting on your point number 2. I almost put that as well. AKL, WL and the Grand Californian are the three best themed resorts I can think of. The imagineers just did a superb job on those resorts! And all three have or will have DVC!
And they all have the same architect. I can't think of his name. He is also the architect on the Hawaii DVC resort.
