Those are my favorite ships, unfortunately all the suites are located under some passenger area. The worst noise I ever had was under the tiled area of the Windjammer. We were kept awake by trolleys being pushed across those tiles at 3am. I think under the pool would be preferable to that. I usually try to get one of the aft JS cabins. They are under the outdoor eating area, but I’ve never been bothered by noise there. That being said, I have a booking coming up in a midship OS.
