I just cannot understand why anyone would want to "camp" at a KOA or similar RV park. I have stayed at a couple of them while visiting urban areas or attending weddings or other events. In every case, the sites were small. The view is likely to be nothing more than RVs in all directions. Noise is often an issue with kids running around all day and often parties at night. Some people seem determined to have campfires even on warm summer evenings. You can often find campfire stench and smoke just a few feet from your campsite with a breeze blowing it into your face. Let's not forget to mix in barking dogs, outdoor speakers and alcohol.
Maybe 30 people next door is unusual but the rest of what I mentioned is common. I guess some people like this and consider it to be "social".
I cannot imagine why anyone would go to these places and then complain they do not like them. Personally I avoid them. That is why I stop at Cabelas when driving through the area. Even if I were visiting the area to see the sights such as Amish country, or Lancaster archery or whatever, I would stay at Cabelas. It is not about the cost but more about the convenience of a quiet area with water and a dump station. No kids, no dogs, no music, no fires, no crowding, no people hanging around drinking.... priceless.
