I realize I am replying to an old thread but I just signed up recently. Jersey City is obviously the best way to go for NYC but they are sold out often. I would disagree with your next best options of Edison or the Meadowlands. The Hilton Newark Penn Station (not the airport one) is directly connected to the train station (you do not have to go outside). Not only is it connected to the PATH (20 minutes train ride to WTC) but you can also take the NJTransit train right to Penn Station in Midtown Manhattan for $4. The train ride is only 15 minutes, although it doesn't come quite as often as the PATH. I always stayed at the Hilton Penn Station for NYC trips before i moved to the area. My friend booked it on Hotwire recently for $80.
