It's hard to tell what kind of water view some of the rooms have in each building, but a huge group does as a whole. As far as getting a room with a water view and the second entrance to the bath, it is pretty good, but there are some buildings with no second entrance and water view, not a ton though.
BTW, all HH area rooms only have one entrance to the bath. Also, if you really want a water view, you may want to call and make sure you are NOT on the first floor. Many of those rooms have a restricted view (you may feel like you are in the rain forest). There may be water on the other side of the foliage, but you won't see it from the first floor.
