Open Question: The best way to go camping?

I'm from Illinois and me plus 8 other friends wanted to go camping for one night. The only thing is most campsites in illinois only allow 4 people per site and we all wanted to stay together. We tried to do group camping but you need to be a part of a youth group and were not doing that. were all 18 and older so were old enough to camp with an "adult" present. does anyone know where we can find a campsite in illinois that allows a group of nine people? Somewhere close to Chicago or Rockford would be nice.
