Travelzoo offers the New York 6-Attraction CityPass for Adults for $109. (Direct purchase from CityPass costs the same, but a $1 processing fee applies.) That's $74 off list and the best deal we could find on this pass. Use this pass at any time over a 9-day duration to gain access to six New York tourist attractions: the Statue of Liberty, Empire State Building, Metropolitan Museum of Art, American Museum of Natural History, Solomon R. Guggenheim Museum, and Museum of Modern Art (MoMA).
Of note, a kids' ticket is available for $82. That's $58 off list and another price low.
