In the early 1970s, the park was extremely successful partially due to the closure of Steeplechase Park and Freedomland U.S.A. in 1964 and Palisades Park a few years later. Alvin Cohen was now the primary owner of the facility and he bought an additional behind the park for 1 million dollars. Over the next few seasons Cohen increased the ride count from 16 to 30. In 1973, three new thrill rides were built: the Toboggan (a compact roller coaster), the Amor Express (a high speed circular ride) and the Galaxy (a steel coaster). The next season brought on the Wave Swinger, a European-style spinning swings ride, one of the first of the kind in America. With the success of the Wave Swinger, Cohen decide to import more European rides, and in 1976 imported the Enterprise and Troika (both spinning rides). Cohen acquired these rides from Willy Miller, who owned a business importing European rides. Cohen saw Miller's interest in the park, and invited him to buy 110 Adventureland. Over the next two years they negotiated and finalized the sale on September 15, 1977.
