Tasking my niece from Providence to Villanova U for college tour so I can't afford to mess up. We'll be pulling this off in a day, back and forth. Once I get to Philly's Amtrak Station, where do I go to pick up a train to Villanova University? I read something about Suburban trains but I really need to know exactly where to go, how long it will take to get to Suburban train, etc. Any help will be GREATLY appreciated. Thank you. (We plan to make the trek on a Saturday in September, probably the 21st.)
