I just wanted to come back to this thread to point out something that I think people missed: The OP Will only be in WDW for TWO nights.
I too have stayed at both resorts and I prefer Animal Kingdom Lodge. In fact it is my DH's favorite resort. But I think that amenities such as animal viewing, zero depth pool and children's activities do not play a role in such a short trip. Unless, of course, it's a non-parks trip. I love, love, love ALK ... but when time is short I recommend location, location, location.
