My wife and I do a lot of traveling and have come to enjoy the cleanliness of KOAs when we are looking for something more comfortable during a trip.  The KOA in Buena Vista had some nice features such as some unique cabins.  The rest of the KOA was very outdated.  The bathrooms, even when cleaned, still had the appearance of being filthy and broken down.  Unless we needed a quick campsite, I don't think we will be staying here again.
