If you are going to have a car, I would suggest requesting something close to the entrance. We had villa 7004 which was waterside, close to the entrance but quite a long walk over to SSR.
If you are not going to have a car, I would suggest request something close to Grandstand to shorten the walk.
Our water view treehouse was so covered in vegetation that we couldn't see water out any of the windows or from the deck. We had not requested a particular view so it really didn't matter to us.
The pool there is about the size of the one we have at home, it's just a backyard type of pool. If you want a fun pool, you will have to go over to SSR.
