Thank you for taking the time to provide feedback on your tour of Philadelphia. We're sorry to hear that the rowdy behavior of some passengers detracted from your overall enjoyment of the tour. We strive to ensure that all of our guests have a fun and memorable time exploring the city, and we'll take your feedback into consideration as we continue to improve our services. As for the Liberty Bell, we completely agree that it's an iconic symbol of Philadelphia and any of the attractions are separate from our tour and can be visited. We hope you'll consider joining us again in the future.
