OK, OK you twisted my arm.
My wife and I did the Big Nude Boat.
This was our 4th cruise with BN and our last.
The food was just barely OK, just. You could tell the cruise line was cutting corners.
The boat ride and day at the nude beach in Cozamel was very good. A beautiful beach and great food and just plain fun.
In Costa Rica was arranged our own trip that included a river cruise and had a great time.
Panama was kind of dull and the port is very dangerous. We didn't feel sale walking around.

Now the big issues.
1) Just too many people on the boat. Lines for everything.
2) Both Carnival and BN said that unattended towels would be removed after X amount of time. Wrong! We never got to sit near a pool or the movie screen. There were towels on seats all day and no one in sight. When we complained to BN they said to remove the towels outselves. I'm just not going to do that.
3) This trip was mostly sea days and there were just too many people and too few pool spaces.
I know, nudists are sun and pool people ans we are too. No joy on this cruise.

We have been to 5 nude resorts in Europe, many, many Caribbean island and nude places all over the states.
We'll stick to landed vacations.
