Can't Find the right forum for this . . .so it goes here I guess.
Found this website that seems to be an agency that caters to the idea of providing an escort for your cruse in the Caribbean. I didn't dig too deeply, but they seem to book the cruse for you and book a girl of your choice for the trip as well.
The girls seem to be European. Couldn't find a package price or any discussion of money.
