I hate to be the :bearer: (pun intended) of bad news...Carnival did away with their topless deck at least a year ago (if I am remembering correctly).
There are Adult Serenity Areas on the Fantasy Class ships (Inspiration, Imagination and soon the Fantasy and Sensation)....but no topless.
COMPLETES THE FLEET
If it is Carnival and it floats....we have sailed it!
Hubby ... DIAMOND (every ship except the Carnivale)
Me ... DIAMOND (every ship starting with the Tropicale)
20 year old son ... DIAMOND (every ship starting with the Tropicale...he is the only DOUBLE Milestone under the age of 21)
24 year old son ... DIAMOND
