Stayed at Liberty Park for a week and was happy with the location for going to NYC. Subway is about a 3-4 block walk from the park and with advice from the locals, you can get to wherever you want to go in the city. The spots are tight but doable. When we were there they had a night watchman in a tower overseeing the park and surrounding area. The drive in is tight because the streets are close but it is okay if you look out for the crazies. Make reservations well in advance because there are not a lot of sites. Have fun. It is a great trip.
