My husband and I really enjoyed the Hop On and Hop Off tours. The narrators were very knowledgeable and provided interesting
details about the sites, and architecture about each of the stops. We really enjoyed the Ben Franklin Institute, the Liberty Bell, and
the U.S. Mint. Incite into the Quakers and their role in the history of Philadelphia's buildings and the tour of Center City's skyscrapers
were extremely eyeopening.
