Would somebody who does not drink but loves spooky places and ghost stories like the tour?
Yes, you do not have to drink. The tour is informative and Steve has stories galore about many of the sites.
Yes! I didn't buy drinks at any of the pubs. I was holding out for cider and they didn't have any I liked. I thought the pubs gave the tour some nice anchor points though!
It is a partial pub crawl (so some of the stops may have you waiting while others are purchasing beverages), but as far as the quality of the tour, I would say the information presented would be just as fascinating whether or not alcohol is involved.
