I absolutely love the Polynesian & Animal Kingdom Lodge, those two are my favorites. The Polynesian has an sweome Hawaiian theme to it which I love & the Animal Kingdom Lodge is so big & the decor is so amazing! I love how you can see the animals from Animal Kingdom, it's unreal.
I stayed at Old Key West during my last trip, I didn't think I would like it very much but I ended up loving it, it was beautiful. The rooms are very spacious & really nice. We didn't get to use the pool, because it was too cold & it was under renovation anyways, but it looked really neat.
Our "home resort" is Saratoga Springs which is amazing! But I have to say, the rooms aren't very big, I always feel like there's no where to go & I always feels like everyone is on top of each other.
Beach Club is also really nice. I've never stayed there, but I think next time we go as a family we're staying there.
