12x12 is pretty small for 4 people.
Get one of those cheap 12x12 plastic tarps, spread it on the ground and then have your buddies just stand on it.
14x16 would be as small as I'ld want to go for 4 people,unless it's just you and the top 3 Dallas cowboy cheerleaders....
Alaknak look really neat, and are simple to set up, but that polyester material won't hold the heat nor stop the wind the way a good ol heavy canvas wall tent does.
That's actually a really good idea.
Especially the Dallas Cowboys part.
