I stayed there a couple years ago and had a theme park view, which I really enjoyed. We were on one of the wings, the pool was directly below, and to the right we could see quite a bit of DCA. We could see the top of Grizzly Peak, and all of Paradise Pier (the sun wheel and California Screamin').
While I would probably spring for the theme park view again, BF and I walked around the entire resort and agreed that we would have been happy with any view. Even the rooms that overlook the front entrance would be nice because there are lots of trees (although if you call them they will probably just refer to it as a "parking lot view").
I don't think you can go wrong with any of the rooms here.
