Philly to Atlantic city by train
I'd like to fly into PHL and go to Atlantic City for a couple nights. Do I need to rent a car, or could I go by train without to much trouble. If I'm there without a car is there some place budget to stay walkable to the boardwalk. What would be a good hotel price for the boardwalk. Going Aug. 16th 17th or 17th 18th. Any train info and cost would be appreciated to decide vs car rental.
