Individual, Family, Dual Premium, and Family Premium Members receive a discount on tickets to the 4-D Theaters at Central Park Zoo ($4 Member/$7 non-Member) and the New York Aquarium ($3 Member/$6 non-Member). Conservation-level Members have free access to these attractions.
By 1980, the zoo, like Central Park itself, was dilapidated; in that year, responsibility for its management was assumed by the New York Zoological Society (renamed the Wildlife Conservation Society in 1993). The zoo was closed in the winter of 1983, and demolition began.
