We land in Philadelphia on 27th August and don't need to be in New York until the evening of the 30th August. Travelling with husband plus 12 year old and 15 year old. We don't know the area and are wondering if there are any recommended stop off spots over these few days. We were wondering about Atlantic City but not sure how suitable for teens! Would there be any better beach spots, or any 'must sees' on our journey to New York City?
