Tad was an entertaining guide who provided a lot of history on the tour. He also did a great job projecting so that everyone could hear him.
My only problem with the tour was the size of the group. There were over 30 people on our walking tour! As someone who already dislikes crowds, it was an uncomfortable number but with the additional COVID-19 risk, I felt it was an unnecessarily unsafe number of people to have clustered together. On top of that, the guide did not enforce the wearing of face masks. Most everyone had the decency to wear their masks but one man refused so I felt it necessary to make an effort to avoid standing by him as much as possible.
If I had known the group size at the outset, we definitely would not have participated.
