Don't forget that KOA's have cabins. Every time I have ever stayed at a KOA, it's been a good experience. Clean showers, and clean cabins, and every cabin I've been in has had A/C and heat. I think the most expensive one I've ever stayed at was 60 something dollars. You just need to provide your own bedding, which we will all have with us anyway. It would look pretty funny to pull into a KOA with a trailer to stay in cabin, but I'm ok with looking weird!
