We like to get water view if we can get a nice room overlooking the river, which we always strive for. AB 14 or 27 are lovely for example, and so are the water views from Parterre and Oak. True, you don't have a 'real' balcony, but you can still step straight out of your door and the scenery is beautiful. We had an upper floor room in Parterre one time, where we could see the river ferry boats from the window and watch the horse-draw carriages in the evening. Really magical.
River view rooms tend to be the nearest to the main buildings too, which is worth bearing in mind too as it makes them closer to other resorts' concept of a "preferred" room.
But I agree with others in that a view overlooking a "puddle" or fountain is probably not worth the extra money, and we've asked to be moved if we've been offered that sort of room. Pool view is a personal choice; I'd say not really worth it for the view - but if you want quick access for swimming of course, it's great.
But the whole place is lovely anyway - apart from a few parking lot views, you'll be fine anywhere.
