I tried the French Quarter History Ghostbuster Tours a couple years ago with a buddy and his wife and it ended up being a nice 2 hour break from the bars. We stayed in the French Quarter the whole time and away from the crowds but we didn't go inside any locations or cemeteries. They didn't mind anyone drinking and we stopped at a bar about halfway thru for a free beer and to use the restrooms. I don't recall the ladies name but she was pretty good. And speaking of spirits, I believe she had already seen a few earlier in the day if you know what I mean.
