We got this pass after reading several reviews of all the different passes available. We liked having the flex option and the availability of the bus tour and One World Trade (this alone was the reason we chose this pass). You really are not skipping any lines. You should know that several of the attractions have a timed entry. You take your pass, wait in line to get your ticket with a time. This applied to Statue of Liberty, One World Trade, 9/11 and Top of the Rock. If you are going in the height of the summer and you want to wait in some long lines this is the way to go. It would be great if you could enter your sightseeing pass number into the website for each attraction so you could get your timed ticket. We found they did let people get their tickets for another day/time. Had I know this in advance, we probably would have done that. When sightseeing in such a big city, that is not always convenient. The reason for the 3 stars was because when we were waiting in line for Top of the Rock and finally got up to scan our passes, there was an issue with the Sightseeing Pass system. The girl at the register said there was an issue in getting the credit needed from Sightseeing Pass to validate our tickets. There were SEVERAL of us who had this issue and I can't even imagine how many they had after us. We waited about 30 mins for some kind of resolution and nothing. Thank goodness for the employees at Top of The Rock who gave us a resolution so we could enjoy the top.
