We were on the Riviera Deck on the Crown a couple of years ago. We were located under the pool, and didn't hear very much. Every once in a while we heard someone scraping a chair on the deck, but never heard it at night. We thought that it was absolutely no problem being on the Riviera deck.
We were on the Crown Oct 2007 in R719. Yes occasionally we could hear the carts in the Horizon court usually early in the morning when they were getting prepared for the day. But not people or other noise. We were just on the Dawn Princess and our room once again was under the Horizon court and we definitely had more noise. We will not do that again. Maybe the new ships have more insulation.
