Unless you are using all the vouchers in the booklet (Top of the Rock, Statue of Liberty, American Museum of Natural History, Empire State Building, Metropolitan Museum of Art, Intrepid Air & Space Museum OR 9/11 Memorial & Museum), you're best off buying the individual tickets at each venue. In my visit's case, we only used 2 (Top of the Rock and Statue of Liberty) as, for example the Modern Museum of Art (MoMA) is not included in the booklet. So, do plan your visit, and if you're going to ALL the attractions included, by all means go for it, otherwise, it's just wasted money.
