Spent a week this summer at Campland on the Bay in San Diego with 3 of our children, their spouses, their kids, a few friends...the RV was the basecamp and each group had their own tents. Sure, the kids teamed up but that was their choice. Everyone was expected to help and everyone did. It was exhausting! But after doing this for a few years I have learned not to try to "herd cats." And this type of camping is limited to once or twice a year.
But again, everyone brings their own sleeping place, and everyone pitches in.
Best to you and Happy Trails.
