I have most of the basic plot for this organised, I'm just struggling to think of a couple of things. Characters are an eclectic bunch of guests and crew on a 200ish guest cruise ship in the Caribbean. The ship is going to be boarded at night by about 20 mercenaries who will arrive by a small boat and have a few people on the inside to disable communications, etc. Their plan is to extract a VIP and escape on their vessel. The problem I have is how to transform this into a full-on mass hostage situation when the mercs end up taking over the ship because they can't leave or decide not to. Does anyone have any ideas for a plot device that will change the game enough? Also can't decide who the VIP should be and who's paying the guys who are boarding the ship. It's obviously someone very well financed so I was thinking drug cartel but I'm yet to settle on a plausible motive.
