Notes: We two were very happy in our cozy cat 11. The only time we bumped into each other (unintentionally!) was in the little entry outside the bathroom door - I might try a 'sideways' config next time.
The closet light never did go out, so we always had a little light and it was fine. I didn't miss having a window like I thought I would, though of course a porthole would have been wonderful!
The telephone was dicey - you had to hold the wire in the back just so in order to hear.
A couple times during the day I heard noise from surrounding cabins, but it was very muted - you couldn't tell what was being said or where it was coming from. It wasn't a problem. I also heard the kids' club above occasionally, but again, very muted and not a problem. I was never awakened by noise.
I loved the location - no more than 3 decks away from the action in either direction. I would definitely stay on deck 6 again. Maybe a tiny bit closer to the elevator, but it was even nice being sort of in the middle of the mid- and aft- elevators - we could choose which to use.
