I agree that the Riv Deck is excellent, as we usually wind up with a cabin there. Less motion, and only one deck away from all the action at night! Having said all that, there are a couple of areas that I avoid, because of possible noise. I usually won't accept one of the first 4 or 5 cabins in the bow, because it's so close to the big lounge (I'm referring to Spirit Class ships). Also, I've found that on those ships, the Starboard Side cabins are better, because on the deck above, on the Port side forward, there is a Jazz club, and you'll occasionally hear noise from that club, if you're directly under it. Other than that, Riviera Deck is truly excellent!
Have a GREAT cruse.
