Hi, we are going on a cruise through the Mexican Riviera on Norwegian starting in LA.  My son has to get off the ship early due to another commitment that has come up.  I called Norwegian today and they said it wasn't possible, but then I called back and got a supervisor and he said they can't hold you hostage and people get off and don't get back on for numerous reasons (eg. excursions goes late, fall asleep at the beach, over drinking, etc.).  I am worried that if we make plans for him to fly
