I sailed the Adventure and had cabin number 2300, deck 2, and we loved it! You do not even know you are sailing, it is so smooth down there. We only had to walk up one or two flights to be where everything is, or of course, used the elevator. It was so quiet down there also.
We liked it so much down there, that we have chosen deck 2 for our cruise coming up soon, and deck 3 for our future cruise. (These cabins are identical to the ones you pay more for, just to be on a higher deck.)
We had the cabin under the photo studio, because we knew it would close early, and there would not be any noise overhead.
I hope this has helped you.
