Travelzoo offers the New York 6-Attraction CityPass for Adults for $109. (Direct purchase from CityPass costs the same, but an extra $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). This booklet must be redeemed by February 28, 2015.
Of note, a kids' ticket is available for $82. That's $58 off list and another price low.
