We were on the Jewel OTS two weeks ago (same class ship as Radiance). We were in cabin 1600 - aft suite directly under Windjammer.
We heard noise from the Windjammer one morning about 5:00 a. m. Must have been the crew cleaning. We could hear them dragging chairs around for about 10 minutes. Never heard another sound any other day.
Personally, I wouldn't give up one of those great aft cabins on deck 10 on the off chance you might hear some noise above you.
