<p>The mnetronorth is definitely cheaper . When you get to NYC purchase an unlimited metrocard $7 for day pass, $21 for a weekly pass an jump on the subway as NYU, Fordham, Columbia, Barnard Parsons, FIT, Eugene Lang are all assessible by subway.</p>
<p>You can take the NJ tranist train fom Penn Station to Princeton.</p>
<p>If you choose Amtrak as an option, I would suggest going to <a href="http://www.campusvist.com%5B/url%5D">www.campusvist.com</a> </p>
<p>because they have promotions with amtrack </p>
<p><a href="http://www.campusvisit.com/amtrak/%5B/url%5D">http://www.campusvisit.com/amtrak/</a></p>
<p>where if your child is visiting colleges and taking Amtrack it is buy a ticket, get a ticket free (7 day advance purchase, not valid on the Acela or Metroliner) . Blackout dates are FEBRUARY 18-21, 2005; MARCH 24-28, 2005; MAY 27-30, 2005; JULY 01-04, 2005; SEPTEMBER 02-05, 2005; NOVEMBER 22-29, 2005</p>
<p>Through campus visit you can also get discounts on various hotels. Some even allow you to comine discounts (AAA).</p>
<p>Just map our your trip and have a good one.</p>
