I know a few people who have. Below decks off hours is the ghetto house party you would expect. The stories I heard were a cross between living in a closet sized frat house and being an inmate in a super max prison.
A chick I know used that as a spring board to the merchant marines. She ended up doing supply runs for the USN to the the ME making good hazard pay. They all set up residency in FL for cheap taxes. No rent, no bills and no place to spend your pay check. After 8 yrs she retired with a fat bank account and 2 houses paid for. She was a decent looking woman, I am guessing she probably banged a boat full of dudes every trip.
