We stayed at a KOA in Sweetwater, TN and although it was expensive (to us) it had wifi and cable. After traveling all day we decided to try another KOA and found this one at Batesville, IN. We don't know how much KOAs in general have gone up in price, but this one was $65, had stone gravel sites that weren't totally level, had no cable, hard to access dump station (our site at this price was only water and electric), and no wifi as advertised. We called the Quality Inn not too far from here and the price was only about $7 more! However, we couldn't cancel and get our money back because of their policy. This has helped us decide that KOAs are not in our future. Can't figure out how to add pictures or I would include the screenshot of the site saying they have wifi. https://koa.com/campgrounds/batesville/
On a good note, the woman helping us was very nice.
