If you haven't already made reservations at the campground, get busy. They fill up very quickly. When you make your reservations, it may be an online reservation system, but give the campground a call to find out how far the water connection and electric is from your site. At one of our fav SPs in KY, the water and electric is between sites and you need extra lengths of both. Apparently happens often enough that they keep a supply of electric and water supplies at the guard shack and loan them as needed. Lots easier if you know this ahead of time. Have a great time!
