We were in 7082 and my MIL and FIL were in 7080 when we cruised in Jan 2002! They were great cabins! Never heard any noise, very quiet at night and we never had any problem with motion. I'm especially prone to motion sickness but I never experienced any problems at all in these cabins. They weren't particularly close to any elevators but again, this wasn't an issue. In fact, maybe this was an asset because we didn't have to worry about people running down the halls or being noisy coming off the elevator. Housekeeping was great; in fact, I don't even remember even seeing our room steward.
Tell your boss that they will have a great time!
