We chose this tour because of the great reviews and were hugely disapointed. We joined a group of other three tourists, so there were only five of us in total. The guide told us close to nothing about the history of the USA, and only pointed at certain places of interest and told us the names of people that lived or worked there. We went from one house to another in total silence. Yet when we walked into the Christ Church, we were enchanted by another tour guide telling stories to her group. Unfortunately, our guide rushed us along. It is either a poor script or a poorly trained guide, because there is no luck of history there.
Although listed in the tour description in TripAdvisor, the visit to Independence Hall was not included. Just as well, as we had an excellent guide there on a later (free) tour.
Our advice - look for a better tour company as the history of the place is fascinating.
