The guide we had was extremely knowledgeable. Not only was Sydney entertaining, but they also made sure to engage everyone in equal amounts and made sure everyone got a chance to share their thoughts and questions. Myself and my family really learned a lot. It was more than just your typical founding fathers' tour! We all walked away with another perspective of the founding of our country.
Also, the tour was so engaging, the kids in our group didn't mind the walking and the teens didn't reach for their phones! Very impressive.
