You can walk to ASC from Newark Penn
If you are taking NJ transit, get off at Newark Penn Station. If you are taking PATH, it is the same stop again. (I think that's the last stop for PATH in NJ). I walked to the ASC from Newark Penn station for my FP and it took less than 10 minutes. But I don't remember the exact directions as it was some time ago. But it is very close to the train station, not worth the cab fare. If you can find a phone # to the ASC, you can ask them for walking directions from Newark Penn.
