Maybe you should expand on what job it is you're doing?
It's fair to say, congratulations - the cruise lines don't employ idiots. There's not enough people on board to have people along for the ride, so the fact you're there at all means you
are ready for it. (So don't let anyone with an agenda try to convince you otherwise!).
In any position, remember that the entire cruise industry's number 1 priority is customer service and satisfaction. Everything else comes second. Like - especially in the case of lower ranks - if a passenger makes a complaint about you, there's a good chance you'll be in
line for a plane ticket home pretty soon. Your side of the story is not particularly relevant or even desired. So don't give them any opportunity to penalise you... there is a long
line of people waiting to take your gig so it sadly is one of those gigs where it's fairly easy to be fired. So you know, the obvious - turn up in the correct uniform, turn up on time, don't turn up still pissed from the night before, try to get on with your colleagues, treat equipment as you would if it belonged to you, that sort of thing.
Also rule number 1: never ever ever ever go intimate with a passenger. Even if she is an absolute goddess in her swimsuit and in the bedroom, even if she is 6 leagues above anything you could bag at home, even if she is like front-cover-of-playboy material, victoria's secret model standard, absolute perfection of the female species... still do not even tempt yourself unless you are looking for a way to get off the ship quickly and permanently. Sometimes attractive late-teens / early-20s girls cruise with their family and whilst sure, they'll enjoy the attention of a strapping young lad from the
theatre; her parents - if they find out - will be straight to the complaints
desk. Some out of principle, and some to try and levy some extra spending money out of Carnival by way of an apology. Even if you don't "do the deed", being seen leaving a passenger cabin is basically taken to mean you did. And remember some ships have
CCTV coverage these days so you can't even
sneak about... So seriously, don't. There will be plenty of Asian and Eastern European ladies in the crew areas gagging for some western male attention (and a green card...) to take out your frustrations on.
