My first cruise was work. Got paid to be there, and the boss picked up the fare. But that was back in 1980, and that ship didn't have phones in the cabins, and of course, no internet cafe in those days.
Sorry, my mom the frequent cruiser is rubbing off on me. Her standing orders are " if I am on a cruise, don't call me. If the house burns down, I will deal with it when I get home. If anyone dies, there is nothing I can do about it, I will deal with it when I get home" and my personal favorite.."if I die on the ship, make sure they leave me on board, because I paid for all 7 days"
