We've stayed in our fair share of KOA's. When we lived in Illinois, most of the parks were overrun with party crazy people, children running amok, and boozy campfires at night. However, we've stayed in some fantastic KOA's in other parts of the country. I also think it's really location, location, location and how well the owners/staff keep up the place. They are an expensive option.
