We took a tour with the same company last year and had a wonderful experience. This time, not so much. We had to wait 30 minutes for a group that was late, there was very little training beforehand, my daughter and husband fell, one tour member's Segway died and the group had to waste time waiting for a replacement, AND this is NOT a haunted tour. The guide had very little interest in telling about ghosts. Just a little history and architecture.
