9245 directly overlooks the smoking area on deck 5. We could watch the people smoking and could smell the smoke. X first said that there was no smoking allowed, but then admitted that we were over the smoking area. We were moved to a suite due to a flood in the room and the smoking area below us. Room was directly at the curve of the ship, so the balcony was not very private, but seemed to be slightly larger than others due to the position.
Check out odd numbered cabins near the rear elevator to make sure you are not directly over the smoking area. Some cabins looked directly at the smokers a deck below them.
