We stayed in an ocean view cabin (3548) on our Adventure cruise last fall. It had a nice large window, and we didn't hear much from the cabins on either side of us. We were very close to the theater at the front of the ship, though, and could occasionally hear parts of the shows. We also got a LOT of motion in rough seas being that far forward.
I would stay in an ocean view again, although more midship or aft.
