About 14 cruises with cunard on all their ships ,i really had to think hard about cabin noise etc .....one had vibration from a diesel ,one had noise from some type of machine,one was close to crew stairway and one was too near the child day care drop off in the morning . I noticed it but none disturbed our sleep .I would only advise to avoid deck 6 port/aft qm2 so you do not get run over in the morning by a lil ninja lol.
