I'm working on a mystery that involves a woman pretending to have gone overboard off of a cruise ship. The ship makes a port stop before she is reported missing, so she has a chance to get off before the alarm is raised and they search the ship for her. The thing is, I can't have her go ashore with the passengers, because her little swipy-card thing would be swiped as she got off the ship. I need her to get off some other way, like maybe with some garbage, or something else handled by the crew. Suggestions, anyone?
