Hi there, not sure that there is such a position per se.
All the escorts we have chatted to from different cruise lines all work on board (dance troupe, entertainment, shops, officers etc) and basically give up their own free time in exchange for a 'free' place on the tour.
If you do hear of a job that entails just going on tour as an escort, please let me know
