I am leaving next week for my cruise of Cape Liberty and had a very difficult time finding transportation to the pier. I am not sure where the subway system is in relation to the Newark airport but I ended up finding a van company to take my whole party for like around $25pp roundtrip. I can give you the name of the company if you are interested. I found out through my research that most companies in NY can't drive you to New Jersey because their license only permits them to drive to Newark airport and back to NY. On the other hand, taxi cab was going to be $40 ea way. We have 7 people in our party so that was not economical for us. Hope this helps.
