Stayed on the Riviera deck once. Plus - you are close to disembarkation (at ports of call not necessarily at the end of the cruise.) You are also closer to the lobby deck - a plus if you like the ground floor of the theatre. We always used the stairs except when going to the Lido - and did then a couple of times.
Minuses - on our cruise there seemed to be a lot of large groups with kids (it was spring break) so there was a lot of door slamming. Of course it was spring break so that might have been the case all over the ship. We did hear the ship drop anchor once. We also salied through a tropical depression and felt the motion of the ocean, but perhaps less so than the upper decks.
