Unfortunately we booked for only one day. It snowed the day we had the hop on hop off bus and there was too much snow to see the Statue of Liberty and to go to the Empire State Building. Very disappointed! We got to the 911 Museum and the line was awful plus the snow and ice in the waiting area. We missed the things we really wanted to see. We were under the impression all we had to do was show the pass you sent us to get on the bus. Not so, we had to go to their office to get a pass to get on the bus. With the weather like it was that was a chore. Thank goodness it was not far from the hotel or we would have been in trouble and would not have been able to get on the bus. Unhappy we did not get to see the things we wanted to and that is why we purchased the pass in advance. We will know better next time.
