Our guide, Tony DiSante, was excellent. He gave us a complete overview of the area as well as the events of 9/11. Although we did a lot of walking, the pace was good and as an older adult I could easily keep up and hear him. It was a cold, windy day but we took a route that kept us inside as much as possible. The tour was very well run, with good directions for meeting and timed tickets that eased our entry into the museum and One World tower. A great way to experience the 9/11 site!
