The pass was good and encouraged us to do things we wouldn't usually, for example the bike ride around Central Park. It didn't allow you to upgrade to the skip the line at the Empire State though and we found the 3 day one wasn't enough time to make up the cost of the pass in entries and tours.
I was extremely glad that we bought these passes. We bought the 2 day pass and tried to cram as many activities as we could in these two days. We did far more than I think we would have if we had not have purchased this pass as it saved us lots of money and encouraged us to try things we maybe wouldn't have tried if the pass had not got us entry.
A trip of a lifetime - what an experience! The New York pass allowed us to visit all of the sites we had planned plus others along the way. Absolutely exhausting but so worth it.
