The booking process through Liberty & Co.'s Website was easy and straightforward, and they offered a 25% discount for Memorial Day weekend (so it came to about $33), as well as a hardback copy of the Constitution for $5. The tour guide was outstanding as a flawless portrayer, in full costume and character, as James Madison as he was in 1794. His knowledge iwas deep and wide, and he made every story engaging as he guided us to the Liberty Bell and outside a number of sites such as Independence Hall, the First and Second Banks of the United States, and the Todd and Hamilton Houses and a number of interesting spots in the surrounding neighborhoods of Washington Square. Liberty & Co. also operates a nice souvenir shop.
