We saved so much money by using the New York pass. We bought the 1 day pass as we only stayed the weekend but we managed to see so much. (Statue of liberty, Empire State building, Madame Tussaud, Top of the Rock and the Guggheneim museum). I highly recommend the New York pass for those who intend to visit the City.
The pass is a good idea but we only got to use it one day as we had to return on the 2nd day after getting the tickets for Liberty isl only to be told to use them on the 2nd day as the ferry was gone. this ment we had little time to use it on that day. It would have been good if you could have used it the following day.
Everything worked fine, could be more informative on where to get your tickets, not that clear we had to ask. Ellis island tickets were at the gift shop nearby and not the official ticket office. plus the boat trip/taxi not clear aprt from that very good
