My mom and her friends go on Witness only cruises every year. Not singles though.
I've always imagined these things being tedious ... but its only real recreation my pioneer mom ever gets so I'm grateful for them.
However, a JW singles cruise with relatively young travelers could be interesting for someone who ... uh, might want to capitalize on all the pent-up sexual frustration. With a lime, some salt, and a bottle of Tequila ... you could basically screw your way through the entire ship.
Hmmm ....
