I've RV'd for over 40 years and have stayed in MANY KOA's during my travels. Honestly I've never had a bad experience in one. With the exception of the KOA in Sugarloaf Key, my stays have been single night stays during the course of a trip and many times they are conveniently off a major thoroughfare. Everyone has different standards and mine are not too stringent. As long as water, sewer, and electric work and I don't have to park in a mud hole I'm satisfied. I have found for the most part you can't depend on the wifi in any park nor the TV service. As far as the pricing, they will charge whatever they can get, it's supply and demand. Of course the cost is higher in popular destinations, wouldn't expect to pay the same in non-tourist areas as you would in the Florida Keys.
