Vash, Charleston is also filled with lots of other things to do and see. The boat ride to Ft Sumter is a treat. The Yorktown is also pretty cool, and The Hunley is also there. Folly Beach is nice, and you have to do a carriage ride. I take one every time I go. At this point, I think I know the tours better than a lot of the guides.
Oh, and I like to stay at The Vendue. There's something about those high rice beds and antebellum rooms that makes me start panting and perspiring, lawt!
