I'm a grad from William and Mary in Williamsburg so I spent a few years there. In terms of ghost tours, I recommend the Colonial Ghosts tour. I know they're run by locals and I found the tour a lot of fun. We had a nice dinner at the French Bistro, Blue Talon, then met the tour nearby for our ghost walk through Williamsburg and the W&M campus. My favorite spot along the tour was the old jail where Blackbeard's pirate crew stayed back in the 1700s.
Also here's another spot to check out - Williamsburg blacksmiths for colonial wrought iron works with authentic reproductions from the era.
Enjoy!
