Here things are measured more in minutes than miles. I live 10 miles from the Lincoln tunnel, it can take 30 minutes to over an hour to get in. You could stay at the doubletree in Newark, take the train from the airport, and then the path from right by the hotel to manhattan. Jersey city/weehawken hotels are right across the river from manhattan, you can take a path train from there, or a ferry. Cabs do not like going back and forth and if you can find one it will be pricy (they’re not allowed to bring folks from NY back to NJ and vice versa).
