Steve, We have stayed in the area, and cannot remember the park, or the goodies they have, it did have smaller sites tho.
However, did stay in Statesboro Georgia for a week, I think only one park there, they are attached (sorta) to a hotel. Grassy sites, full hookups, level sites, not sure what they might have about wifi, etc.
I was doing research in the library at Statesboro, (my great great grampa was born there), so proximity to library was more important to me than wifi, etc. And, this was in 2001 and believe me, the availability of wifi and internet and such is much different now than it was then. That year I did ALL my internet/email, etc IN a public library. The next year, 2002, I was in public libraries near major towns (Norfolk Virginia is a major town, don't cha think??) and they had no internet at ALL! Hard to believe, BUT TRUE!
Anyway, the place in Statesboro, I thought was very pleasant and rather quiet at that time of the year (mid January).
We did have some chilly weather tho. Had to keep the warm clothes handy, no shorts weather. As much as I love the area, and Savannah too, it can be rather cool and of course, damp!
After the Rio Grande Valley last winter, I am not sure I will get back to Georgia in January or February ever again! Need to get back tho, have some more research to do there.
Re-reading this post, I see, it is not much help. Sorry. You will love the area tho, it is beautiful. Drive up to Charleston and be sure to visit at least one of the plantations in Charleston area! They are fab!!
