We were in 6147 & 6647. This was our first cruise so I can't compare it to a std cat 11 except that we were in my sister's room (5501) and her room seemed like a walk in closet compared to ours which seemed like a normal hotel room! We were shocked at the difference. Of course, her cabin was wall to wall people at the time we were in it (all 10 of us either in the cabin or the hall!) We had all 10 in our cabin and never felt crowded!
I tried to get more info before our cruise, such as the actual size of our cabins but I never found it anywhere. And we only have one picture of our cabin....I really regret not taking more photos of the cabins & the ship!
Now I'm afraid we're going to be disappointed next year in a reg. cabin. But we did get one secret porthole room so I'm hoping that makes up for the room!!!
So...if you ever get assigned a handicap room, it's as good as an upgrade in our opinion!
