This tour gave the background of most of the "residents" and at the tomb of the Voodoo Queen. At her tomb we heard the superstitious practice of granting wishes by doing something at her tomb.
I thought the tour guide was knowledgeable but at times lacked the charisma some other guides I have come across in my time have. Regardless, I think this is a must do in New Orleans - a great way to learn the history as many stories are among the graves.
This was an amazing tour if you like that sort of thing. My husband and I had already been on couple of different tours so we were afraid that we had heard it all already but our tour guide was very informative and was always ready to answer any questions we had despite the fact we were melting in the sun. HAHAHA.
