I feel like the story would be the most interesting with a loose group of friends. Friends with some, acquainted with others and probably a few people that are just at each others throats for some personal reason or another; Until Dawns crew being the best example.
If we're following the Until Dawn example then I wanna be the old dude who lives on the boat and knows what's up but still gets his shit pushed in anyway.
Or Peter Stormare. Dunno how he would fit though.
