I'll chime in. It is a great place and you will have a great time.
The mosquitos can be incredible there, so having a thermacell and plenty of refills is a good idea for stand hunting.
There are lots of stands on the property. I always use a tree stand harness and I have my own attachment system for attaching it to a tree. In addition, you may want to bring your own tree stand (climber or steps and a hang-on) in case you see a hot spot that needs a sit. Stand hunting seems to be at its best in the afternoon and up until dark, but weather frats and such may have an effect. You can see hogs at any time because they are always hungry and looking for food.
I would not hunt without either camo or muted plaid. It just makes you a bit harder to see and tilts the odds you way.
Towels and fresh bedding (sheets, pillowcases, blankets) are provided and the place is very clean and tidy. You have no worries on that front. Bring your own soap and so forth.
It is starting to warm up fairly well at the end of March, so clothing for cool-to-warm temps is best. It won't be really hot (90-plus) or really cold (below freezing). But spring in the south can be pretty variable, so be prepared. I always check the long-term forecast before I leave and pack accordingly.
Average shot distance? I would say between 10 and just under 20 yards.
The size of the vitals on a hog depends on the size of the hog.
The countryside there is beautiful. Don't forget to pack a camera.
