Terrible experience all around. Prior to this trip, I contacted a Viator agent to explain my wife was recovering from knee surgery and was able to short to intermittent walking. I inquired how close the stop on the tour were to each other and was advised the stops were all with a block of each other and there would be opportunity's to stop and rest at each location. The tour started out ok with us meeting up with the group and getting checked in. The guide started her stories which were just meh as her delivery of the stories flat out sucked. We finished up at our first stop at the Cherry Street Tavern and started out on the rest of the tour. Expecting to go just down the street to the next stop. We proceed to walk approximately 5-10 blocks in a big square to go to the next stop which was down the street a block over. Our guide never once stopped to make sure all the group was together and to check on everyone. She flat out hoofed it over these blocks. At one point my wife and I we so behind, we lost the group as they rounded a corner. Again no consideration of the guide to ensure the group was still together. Not know what direction the group went, my wife and we forced to abandon the tour and get burned on the $50 we spent for a terrible experience.
