Pick the theme you like and go with it. One is as nice as another, really.
The one and only trip DH and I made alone, we stayed at Wilderness Lodge. He's more a WL kind of guy. We were thisclose to staying in the Ft. Wilderness cabins, but the WL just has a little more to offer (even though the cabins are nice and quiet.)
When I go with friends, I almost always end up at the Poly. It isn't my favorite, but everyone else likes it best. And I love laying out at the quiet pool and listening to that music.
My favorites are AKL and the Beach Club. I used to give BC the nod, but now AKL is more my style. That's my favorite.
You just have to go with what you like. You can't go wrong.
...unless you pick the Contemporary. IMO, that place is horrible and the WRONG choice - especially for romance. It's just a terrible hotel.
