The park's success was steady until the late 1960s, when the park's attendance was decreasing. Lake Compounce remained under the ownership of the Pierce and Norton Corporation until 1966, when Edward G. Pierce sold his share to the Norton family. The Nortons owned and operated the park through 1985 and were able to restore some profitability and raise attendance. No major attractions were added during this time, and the Nortons listed the park for sale in 1984. In 1985, Lake Compounce was sold to the Hershey Entertainment and Resorts Company, owners of Hersheypark in Hershey, Pennsylvania, who briefly renamed the park to "Hershey's Lake Compounce". Factors such as poor marketing, low attendance, and repeated ride outages caused Hershey to sell the park after two seasons in 1987, a decision that upset local representatives.
