Myrtle Beach is akin to Pigeon Forge, but on a coast. It's a hyper tourism mess. There is good golf around it which attracts some. Calabash just north of MB has classic fried seafood.
Charleston is "historic", as is Savannah. Both are quaint, somewhat touristy now, worth strolling about some. Hilton Head is more our "style". Savannah has a large historic district with some interesting old homes and parks.
Brunswick, GA is kind of interesting and St. Simons and Jekyll Islands are nice.
