we lucked out and had another group cancel, so our tour was just the five in our party (one 18 yr old and four 50-somethings). we had a blast. Kelsey was engaging and not too serious. We're all a bit irreverent ourselves, and our son knows tons about ghosts and the occult, so the conversation was great. There were instruments to use for our investigation -- which we thoroughly enjoyed. A short stop at a pub. 2 hours pretty exactly.
