Penster, you will love Savannah & Skidaway SP. Here is the write up I posted after our 2013 trip.
Over Christmas, Sharon & I took a trip to Savannah, Ga. Neither of us had visited Savannah before and this trip proved to be an excellent 4 day / 3 night trip for us. It's a 5 hour drive for us that took 7 hours to arrive due to the heavy southbound I-95 traffic from I-95 & I-26 exchange to Savannah Exit at HWY 17. Regardless of the delay it was well worth it!.
We stayed at Skidaway SP just about 15 mins southeast of Savannah. Skidaway is an excellent SP with roomy, level campsites and a beautiful canopy of moss draped trees. This SP has some sites that are full hookup, our site had E/W/C. The bath houses were nice. The only issue I have is the nonsite specific reservation system. I didn't like it in Va and Ga has NOT changed my mind.
Savannah is a beautiful and charming city with lots of culture and history. FWIW, While in the area, we visited Fort McAllister and Tybee Island. We had dinner at North Beach Bar & Grill on Tybee Island. This off the beaten path hole in the wall is my kind of place. The kind of place with FROSTY beverages, laid back atmosphere, excellent food and accomodating service. Fort McAllister has a campground as well. We visited the campground while at the SP. We saw several sites we'd like to stay in should we head that way again. Below are some pictures to document the trip.
Enjoy your trip
