I'm hoping someone more familiar with Edinburgh than I am can help me out here.
I plan to take the Mercat Ghostly Underground walking tour later this week. I'm interested in visiting the vaults and want to learn more about them, but I'm not necessarily interested in the theatrics that seem to go along with some of the other tours. I also really enjoyed one of the Mercat history walks I took earlier this week.
That being said, the Mary's Close tour is so highly rated. Is it worth taking, too? Is it informative, or more kitschy? Any thoughts/advice are appreciated. I would be up for taking more than one tour since they all seem to visit different areas. Any other tour company you'd recommend for the underground?
