What it's really called is a "Tops Optional" deck. It's located on an upper deck near the funnel. There is a sign posted next to the staircase, (ladder), that states "Top Optional Deck, No Camera or Video equipment allowed." It is adults only, and anyone of age can go up there. The wife and I spent some time up there last cruise, and found it's less noisy and a nice place to sun bathe without all the hoopla of the Lido deck. Occasionally there are a few "gawkers," but, let's face it, with 2-3000 people on board, what do you expect? I"ve read that every Carnival ship has this deck. Check it out for yourself and see if you're comfortable with their arrangement.
