Had Group but when scanned the server said it was not valid. She scanned again and the same thing again, so I went ahead paid the bill and now having to try and find out what happened.
It was well worth it. I got the 3 day pass and it allowed me to enjoy almost everything in New York, like the Top of the Rock, Empire State Building, Statue of Liberty and several museums. It also gave 2 day access to a tour bus that went around Manhattan and Brooklyn, which was very convenient, but try to catch it early in the morning it does fill up quick. I will definitely buy again.
