Most of my friends camp with me on my property. We have had as many as 65 people camping in our group. Last Memorial Day weekend, we had 5 people that had never camped before and about 15 that have been camping since they were children.
While traveling, I prefer to keep those groups small, just immediate family-kids and grandkids. We have been asked by a couple of friends to travel together and I have turned them down. They are late risers and my wife and I get up with the sun. That combination does not work.
3 of my kids love camping, the other one not so much.
