From Newark Airport:
It is quite easy to get to Robert Treat Hotel from
the Newark International Airport. The hotel provides
free shuttle services to
and from the airport. One can take a
taxi to the hotel for $11.00.
There are also bus services
from the airport to the Penn Station
in Newark (note that there is also a Penn Station
in New York City). Then you can take a cab or
take the city subway to Broad St. (one stop).
Then it is a short walk to the hotel (50 Park Pl).
If you arrive at
the JFK airport or the LaGuardia Airport, then you can take the
subway or shuttle to the Penn Station in New York City (note that
there is also a Penn Station in Newark). From there you take one
of the New Jersey Transit trains (one stop) to the Penn Station in
Newark. Then you can take a cab or the city subway as described in the last
paragraph.
