I bought a groupon for 4 of us and made reservations that was required. The tour guide had such a great sense of humor and made the tour interesting and very funny. She really explained the system of how it was decided where we traveled in the town. The tour stopped at some of the homes and she described in detail the history and present day residents of the enormous homes. It is very important to make reservations for any of the tours in Charleston and if it is bad weather confirm. This is a very reasonable and fun tour for the family.
