This is a really convenient pass. If you have decided on specific attractions, you can buy the pass and book immediately. If your itinerary is very flexible, you can book in advance based on the situation at each attraction (SUMMIT needs to be booked one day in advance, while The Edge can be booked a few hours before the visit on the same day). In terms of cost, it is really more cost-effective than buying tickets for each attraction individually. However, if you are choosing attractions like MoMA where tickets are cheaper, it is not recommended to use the pass. In my experience, I used it for Top of the Rock Observation Deck, The Edge, and SUMMIT One Vanderbilt.
