I have stayed at a number of KOA's and haven't ever regretted staying at them. I have stayed at several non-KOA's and have regretted them. There is an ex KOA at Olympia that is a POS and they didn't want to upgrade when asked by KOA. There is also an old one at Vantage where we had to look at 5 sites untill we could find one that had all the hookups that worked and they wouldn't give us a refund if we left. Sure glad we had a full water tank in the TT that day.
ScottG, I have stayed at a number of the KOA's here in our state and most are pretty good. I'm not sure which ones you're talking about. Mebbee Kent ?
