We have done the couples cruises in 2013 from Port Canaveral, Tampa and Istanbul. Nudity is allowed around the pool and on a specified sun deck. Unlike a strictly "nude cruise" the crowd runs the range from folks who never take off their clothes in public to full swap swingers. The thing is, everyone gets along just fine. If you're not "in the lifestyle", just stay out of the party rooms. In other words, if you want a nude cruise and the schedule works for you, don't worry about the "lifestyle" element. On the other hand, you and your significant other may just find a new spark...seen that happen more than once. The company that charters these ships is very vigilant about keeping any public "activity" confined to the appointed areas, and if you don't want to go there, just don't go there. On the other hand, if you're a traditional, tree-hugging, back to nature AANR nudist, you may not enjoy the crowd of folks truly having a good time without giving a hoot what you think is "appropriate". Or, you might take a peek in the play room with your sweetie...no one will tell the folks back at the club.
