We were in 5524 on the Wonder. We did hear our neighbors, but they were adults with no children, in our tour group, so it really didn't bother us. In fact one day we even opened our connecting door so we could chat about our group activities.
5524 was quite obstructed and there was a light on the entire cruise. We loved the "secret" porthole, but we had to close the drapes if the light got too bright. I also liked the location. It was easy to get to the elevators, and didn't have much traffic noise. We were across from a luggage room, so when luggage was transported we did hear some noise. We would stay in a SPR again, but next cruise in Sept 2003 we are staying in a SVR, (secret but obstructed open verandah room) cat 7 on deck 7.
