I had the "pleasure" (NOT) of having a cabin on the Riveria deck on a 4 day cruise and it was a serious mistake. Those cabins are the less expensive ones and usually where all the young folks hang out. There were drunken folks staggering through the corridors at all hours of the night/morning. Even in during the day, it seemed they ran up and down the corridors, talking and laughing at the top of their lungs! It was aweful. I would never reserve a room down there even if it was lower priced. I have had oceanview and interior cabins, but I always spring for the extra $20 and get a cabin on the higher decks at least Upper deck.
