My stay won't likely be like yours. First, I drove in while Mississippi was under a blanket of snow. All the roads in Holly Springs and the rest of the state were treacherous with packed snow and ice following a week of unseasonably frigid weather across the southern midwest.
That said, the 2 rangers working at Wall Doxey went out of their way to set me up with a parking place in the practically empty campground, putting me in the youth camp, finding me an extension cord to hook up to power and allowing me access to the group camp for a bathroom and shower.
This was necessary because many areas were either in the middle of renovation, inaccessible or out of service due to frozen pipes. To say these ladies went out of their way to get me situated is an understatement. They were heroines!
The camp has loads of retro charm. A big mid-century lodge, picnic area, swimming lake, frisbee golf and a 2 mile hiking trail around the lake. I enjoyed a walk thru the snow and the comfort of having a safe and caring place to stay during my trip through Mississippi.
I suspect it will be the same for you even if your visit is under far different circumstances.
