With the addition of the rides as well as the improvements to the park, the park's value was high enough to sell. It was sold mid-season to Harris Weinstein in 1985. He also bought the neighbouring automobile racetrack which had been used once a year for NASCAR racing. At that point, the racetrack was razed. It was determined that there was a need for swimming to be brought back to Dorney Park. With the pool being razed 20 years before, the void was filled by a waterpark called Wildwater Kingdom in 1985. It had separate admission and included a wave pool, family water raft ride, several body slides, several tube slides, and a children's water play area. That year, season passes began to be offered.
