My daughter and I land at 9:20am on the 17th and have an international flight at 9:15pm. We do have TSA Pre if that helps. Would it be possible for us to see anything with a short timetable? Not sure how close the airport is to everything. I've always wanted to see the Liberty Bell. I looked at the Independence Hall reservations and the tickets are sold out. It's rather last minute for us. Any suggestions? I've never been to Philadelphia. My daughter is 14. Thanks for any advice you have.
