回複:Thank you so much!
They'll have a rental car. They just try to avoid driving as much as possible.
I show them the link here and now they are thinking about to stay in Secaucus for 4 nights. One of the days, they'll drive to Princeton then come back to Hotel. Is it a good idea? I usually go to NY with business trip and take taxi; so don't know much about local details. Thank you for your help.
