My DD's in-laws are on that cruise!!! Someone posted on her MIL's facebook page to "be sure and post lots of picutres." Luckily she hasn't posted any yet, that is not something I would want to see.
I would imagine that pop ups are not as common as people would think. Unless this is a completely new experience for you. I mean staring at naked people all day kind of takes the excitement out it. I would also imagine that people new to nudism would be very self conscious and nerves may make that impossible if you know what I mean lol.
That is one cruise I might actually lose weight on. I would seriously have an issue with eating off the buffet near all those lose pieces and parts hanging around.
I found a hair in my soup ( I'm sorry I couldn't help myself)
