Booked a one nighter on our way through. Unfortunately we were placed in between folks who are there full time and at 4.30 am, yes 4.30 am they started up their old diesel truck and left it running for 15 minutes before leaving. I rang that evening to give feed back to the owner who was completely unsympathetic and told me if I didn’t like it book somewhere else. He actually hung up on me, very unprofessional. Suffice it to say I’ll be talking to KOA customer service tomorrow.
