This is a WALKING tour of 5.5-6 miles!!! It should be listed in the title that it's a walking tour, not way down deep in the bowels of the information. As soon as I realized that I bought the wrong trip, I called and switched to the bus tour for $99. The rep made it seem as if I was going to get a refund, but they refused. I'm 66 and disabled. The spot could have been purchased by another person and probably was, but Viator has a 'too bad for you' attitude. I had a tour in Boston and purchased another one in Washington DC, but after that, I'm finding another app.
