I'm not sure what you mean by 'not enough space.' Have you ever seen a car full of clowns (or a VW Beetle in the 60's?). Space is a commodity, especially in the US. You can fit 20-30 folks in a typical house if you really need to. Or look at the Navy and the term "hot bunking."
Sleeping on the floor is always an option. I was thinking about some of the other logistical problems. Is there enough space to store all of our needed supplies? Where do we cook for so many people?
Oh, as for safety in numbers. EVERYONE should know how to shoot the guns. If only 2 people do, it's not that hard for them to get shot. Remember the scene at the end of "The 3 Amigos?"
Point. I have tried archery and I have good form. I have never transferred that to a gun.
