I've seen campgrounds over the years that dropped their KOA affiliation for various reasons. In some cases, it was KOA's decision when the CG could no longer meet their standards and refused to upgrade, in others it was the owner's decision when profitability dropped, and the 10% fee to KOA became a burden, and in a some cases, it was because the CG had built a good reputation with many repeat and seasonal customers, and didn't feel that the value KOA added was worthwhile any longer. One other reason is a change of ownership, with the new owner wanting to go in a different direction. On the other hand, the KOA roster of campgrounds continues to grow, so apparently more locations are joining KOA than are dropping out.
