As has been pointed out, the overwhelming majority of the views are of the woods. Which is appropriate since the theming is the Northwest and all the trees are pine trees.
Spiceycat nailed it.....ask for a room near the elevators and that's your best bet. You can also ask for a room on the Bay Lake side (same side as the pool) if you'd like. Couldn't hurt.
Room requests are supposedly filled in the order received and in the order given on the phone. So if a pool view is your top priority, you should request that. But that would come ahead of other requests such as non-smoking, etc.
Since so few rooms have pool views, I prefer to go with the wider choice of "near the elevators" to give the room assigners more to work with.
Good luck!
