I have stayed at Sand Hills two years in a row. The water to the entire campground was shut off several times without warning, even though management knew they would be shutting the water off hours in advance. One year there was a grand total or three of us in the campground. Not hard to let us know they would be shutting the water off before getting the shower. Second year I called to make my reservation. The lady who answered the phone reserved the wrong days. When I called back to ask her to correct her mistake she charged me a rebooking fee to correct her mistake. There was garbage around the campground including a shat pair of undershort. Every morning a campground employee who turned the sprinklers on walked past the garbage on his morning walk. The bathrooms and showers were never cleaned. When you check in you are treated like an unwanted guest.
It looks like the campground was owned by a very good guy for years, which resulted in people coming back for decades. Then he sold and the individual spaces are now privately owned, but managed by the Lady Tremaine of the year.
IDRV runs a better campground and treats you like a guest.
