Simon lead our ghost tour and was engaging and engrossing. He is confessedly a true believer in the spiritual world and therefore brings an authenticity and credibility to his narratives and retellings that enrich what might otherwise be rather mundane stories.
The tour covers a great deal of territory in the dark so be sure to wear comfortable, sensible shoes, and, depending on the weather, light loose fitting clothing to stay cool. Insect repellent is a good idea as Charleston mosquitos apparently like to come out in the evenings.
The Unitarian graveyard is wonderful and the highlight of the tour. It is, very cleverly staged as the last stop of the tour so if you are slightly underwhelmed by the first part of the walk, don't give up, the graveyard is a great experience.
The only downsides of the tour were group size and competition. Our group was approximately 20, which is too big for ghost walk as excursions into the spirit world are best as intimate experiences. On the first part of the walk, we continuously bumped into groups of 'ghost walkers' from other touring companies which was distracting. The Unitarian graveyard was, however, exclusive to our tour which was great.
Overall a good experience.
