Old Key West for the much larger square footage than anywhere else but I still wouldn't do it. That's way too many people in way too little space, you're not going to be comfortable. Not enough seating, not enough drawer space, not enough luggage storage, not enough places to kick off your shoes, not enough showers, not enough privacy for the people sleeping in the living room, etc. etc. etc.
I think you would be much better off with 3 studios, and it'll probably be cheaper, too.
