See this map showing the rooms overlooking the boardwalk:
https://www.disboards.com/media/bwv-boardwalk-view.62896/ There are eight dedicated studios and nine 1BRs in that area. There are no dedicated 2BRs at BWV.
As to noise, even in the dedicated rooms, you will notice some at night from outside on the boardwalk, occasional boat horns all day and evening, and boardwalk clean-up crews in the morning along the boardwalk. Inside, you can hear guests who are being noisy when walking down the hall, and a little more from an adjoining lock-off room when occupants are being noisy than you will get in the dedicated, neither of which have I found to be annoying but that opinion varies depending on the person's sensitivity to noise.
