Our family went at the end of October for the Skidaway Institute's open house (UGAs marine science facility). We had a great time. We tent camped with elementary age children.
The bathrooms were clean. The campground in general was well kept. The staff was friendly and helpful. Our site was level and water/electric worked just fine. There's a Wal-Mart fairly close by, the type with a grocery store.
We hiked the trails (be sure to find the lookout tower), biked the campground, and toured the educational center. We also went to nearby Sandfly BBQ, enjoyed that too. On Sunday, we toured nearby Wormsloe Plantation. So, plenty to do and see from the campground.
We will definitely go back. If you are tent camping I'd wait until much cooler temperatures. It is coastal GA so heat and bugs could make for a bad trip at certain times of the year. At the end of October it was perfect for us.
