Be sure that you know that they will charge you if you do not cancel within 48 hours. I broke down in ct and called them to indicate that I would not make it and was delayed for 3 days. When I receive my credit card bill, the charge was on it, called and was informed that is was not 48 hours and therefore the charge.
Have been going to this campground since it opened, and at least 3 or 4 times a year. Not going to make a reservation but will just show up and if no space there are other campgrounds in that area!
