We went on the November 10th 2013 Freedom of the Seas Lifestyle cruise.
We are not lifestylers, but wanted an adult cruise with optional nude sunbathing.
Have to say it was great. Once they hand you over to the cruiseline everything is very much the same for boarding, etc with Royal Caribbean.
We didn't see anything publicly lewd the entire time. And we were out late every night. That was the big difference, people stayed up late and partied whereas a normal cruise goes to sleep at midnight. It was like fantasea fest only tamer as people were more laid back. Lot of lingerie which hubby and I enjoy.
My husband and I did peek into the special rooms and it was what you might expect. We didn't stay but it did give us the idea to hit the bed early.
We met lots of people, but no one was over pushy, and once we said we weren't into the lifestyle sometimes the conversation changed as some folks probably didn't want to waste their valuable cruise time barking up the wrong tree --if you know what I mean.
People were super friendly like any nudist resort.
We would do it again if the right itinerary popped up at the right time of year.
