I am going to Philadelphia with my husband for a long weekend this summer. I used to go to Philly many years ago once a month to visit a friend, but some of the info is now fuzzy. I remember taking a train to New York City for the day, and I would love to do that again. Can anyone help me out and tell me what I need to do? We do not have hotel in Philly yet, suggestions on that would be great too. Thanks.
