The Ghost and Vampire tours are completely different.
(As are all of the tours that the company offers).
The Ghost tour takes you to French Quarter sites connected to actual documented hauntings.
The Vampire tour is a combination of fiction & reality. Fiction in the sense of Anne Rice, Bram Stoker, movie sites from Interview With the Vampire (filmed here)…
Reality, in that the tour takes you to sites in the French Quarter associated with actual Vampire type crimes where people were killed solely for their blood.
Murders, taken from police records, city archives, interviews, etc.
