Once again, the KOA haters crawl out from under a rock. We have a state park near me. They have FHU, Elec. only and dry camping sites. They also have group camping sites and a group camping site with a corral for horses. They even allow visitors for a couple of hours once they check in at the office. All of these campers use different amounts of the amenities and pay different prices.
They did this because some folks would rent one FHU site for the weekend and invite 20 of their closest friends over for a 48 hour weekend party. They also had to pay people to man the entry gate 24/7 because, surprisingly, some people lie.
I'm a solo RVer, but I often stay at KOAs because they're a known quantity. I don't use the restrooms, showers, playground, swings or swimming pool but I find that many offer paved sites with picnic tables, a daily newspaper delivered each morning, free coffee in the office, often a gated entry, a propane filling station, laundry facilities and recommendations and directions for shopping and sightseeing.
So, even though I help to subsidize my state parks through my taxes whether or not I use them, the KOA haters out there aren't subsidizing my CG choices. I'm glad you don't choose KOAs so I don't have to listen to you whine.
