We arrived late to the KOA and attempted to follow the late night registration. Nowhere does it say that late night registration will result in them threatening to call the cops on us. There wasn’t any envelopes. I’ve had that happen many times to me at state and national parks. Never had I had it result in harassment and threats. I’ve always had park rangers catch you on the way out or leave an envelope under the windshield wiper. However this is a KOA and a private campground and are allowed to treat customers horribly, which they did. They started banging on our camper at 3 AM woke up my baby. Threatened to cal the cops for trespassing. When I offered to pay for the site they threatened to charge more and more money if I wasn’t able to pay cash. I was never given a receipt. I was treated like a criminal. When I called them during their office hours that states that it was common courtesy not to arrive after 9. This RV park is along highway 395 so it seems bizarre not to accommodate travelers. They also woke up the campers next to us at 3 am for a similar infraction but state that aside from me this has “never happened”. Save yourself the harassment and threats and a good night sleep and just drive past Coleville KOA.
