I'm thinking that part of the issue is you could get a BW room, have it be far from the water gun game and the boat dock, high enough up that you don't hear the people leaving, etc - and not notice the noise. But since that is a lot of requests and you have no guarentee where you end up, you could end up right in front of the boat dock, on a low floor, with the street theatre happening below your window. No way to really tell.
Or maybe you are used to living on ten acres where the crickets keep you awake - BW might seem noisy where its going to be darn quiet for someone who lives in Manhattan.
Or maybe you go to bed at 9:00 - right as Illuminations starts - its a noisy resort while fireworks are happening. On the other hand, if you are closing Pleasure Island, the BW will be closed when you pull in at night, and mornings are generally pretty quiet.
