After reading the reviews from Trip Advisor, we decided to book the Old City Walking Tour in Philadelphia. Tim delivered more than a 5 star experience! We had a short weekend stay, and were able to see many, many sites while learning a lot of history by this tour, while laughing a lot along the way. At the end of the tour, we ended close to the Liberty Bell and were able to see that, too. If we are ever back in Philly, we will certainly book another tour with him!
