I've haven't been to the Westin or New York but I'm booked in for 2 weeks in May there. From Penn it looks like it's either the PATH or a taxi (or minibus in your case?) Anyway, PATH seems like the best option for transport, that's why I chose the Westin. With 6 people you are better off with a metrocard then a PATH smart-link card, as you get a 15% discount on loading it, and you can scan through up to four people on each card. In Manhattan up to three children 44 inches tall and under ride for free on subways and local buses when accompanied by a fare paying adult. On the PATH Children age 5 and under ride PATH free. Fake it with the six year old. PATH www.panynj.gov/path/index.html(Port Authority Trans-Hudson) is a subway type system connecting Newark and various points on the New Jersey shore of the Hudson River with New York City. Two lines pass under the Hudson and enter the city, one terminating at a temporary World Trade Center site station in downtown, the other at 33rd Street in midtown. The 33rd Street Station was once connected underground to Penn Station, but now, presumably due to security concerns, the underground passage is closed and you must walk a block west on the surface of 33rd.
