Visited a few years back for an Alumni Association Civil War tour.
We studied the last stage of Sherman's march by visiting 3 forts. Nice if you are a history buff.
Spent the first part in downtown Savannah and, when the Civil War thing was over, I went out to Tybee and spent a few nights.
I had a great time.
Savannah was called the most Union town in the South during the war. And, the only confederate flags I saw the whole time I was down there were in the forts.
It was October, which is when the arts college, SACD, hosts a pretty nice annual film festival. So, I took in a few sessions of that.
I remember plenty of restaurants, good walking situation in town, and a pretty nice ice cream shop.
Learned an interesting weather thing while there: Savannah/Tybee is located geographically in a place that rarely gets slammed by hurricanes.
Nevertheless, there was one day where severe flooding cut access from Tybee to the mainland, and I was stranded for a day, missing a film festival session I had tickets for.
As someone said, Tybee is nice, old school, with some old school shore-style drinking establishments.
There are turtle nests on the island, and a marine center which was interesting. Also, a good lighthouse there which you can climb to the top. I did that the day before the flood, which was caused by the wind blowing inland. It was windy at the top, and just about lost a PSU hat...which was snagged by an Iowa Hawkeye fan right behind me. We laughed.
There is also what remains of a 20th century fort on Tybee, which is now a history center.
