Marineland of the Pacific

Six Flags Marineland (1987-1989)
In 1987 Six Flags bought Marineland of the Pacific with the intention of making it a secondary park to complement Magic Mountain.

Failed SeaWorld operation (1990)
Six Flags ended selling the park to SeaWorld in order to put more focus on Magic Mountain and the park was renamed to SeaWorld LA.

Carwardine's OrcaWorld, and troubled operations (1991-1997)
After Amaya Carwardine visited in early 1997, she was horrified at the poor conditions that the park was running it's animals in, demanding the park either become fully corporate owned & operated, or be sold off, the latter was chosen as no one at Carwardine or DreamWorks had any interest in running the park, due to said animal conditions, along with the lack of land to expand the park to justify the rising admission costs, rising taxes in the State of California and heated competition.
