I was on that cruise, and it was absolutely fantastic!! 2300 nudists sailed for 8 days, with 2 days spent at the Fantasy Fest in Key West. I can't remember when I had so much fun. While nudity was not allowed when in port, the rest of the time it was OK pretty much everywhere except in the main dining room. And while Fantasy Fest is well known for having lots of paratial nudity in the streets, with this crowd in port, it was even more abundant. For those who want pictures, here are the ones I posted:
Bare Necessities is having their second Fantasy Fest cruise this year, and my wife and I are already signed up. If you even suspect you might enjoy it, then book yourself a cabin, because I guarantee you will love it.
