This was a gift to my niece and it worked out great for the museum entrances, especially the skip-the-lines benefit.
Didn't really save on queing and we realised that there is no charge anyway at the museums [this is in tiny writing under the recommended donation]. Wouldn't bother with this again.
Personally I didn't think this was the best value, if you are buying this pass, thinking it will help you avoid queuing at the Empire State building or The top of the Rock, then think again, all this pass allows you to do is avoid queuing to buy a ticket, you then join a very long queue along with hundred and hundreds of other people to catch the lifts, for just under and hour and a half before getting to the observation decks, well worth it when you get up there, but paying all this money is only worth it if you going to make use of all the tickets in the booklet, which we did not have time to do
