My sister niece and 2 kids will be going to NYC on a monday while we are on a roadtrip to the NE. At this point I think we will be taking a train from Newark Penn Station and arriving at Penn Station. Will the van be ok left in that area overnight? Is there a better place to park and get to midtown? I've been to NYC several times but always via plane then cab. Any help would be greatly appreciated! We will be coming from Philadelphia.
