No, SeaWorld is not older than Disney.
Here's a breakdown to explain why:
- Walt Disney Company's Founding: The Walt Disney Company was founded on October 16, 1923.
- Disneyland's Opening: Disneyland, the first Disney theme park, opened in Anaheim, California, on July 17, 1955.
- SeaWorld's First Park: The first SeaWorld park opened in San Diego, California, on March 21, 1964.
- Walt Disney World's Magic Kingdom: Walt Disney World's Magic Kingdom opened October 1, 1971.
- SeaWorld Orlando: SeaWorld Orlando opened December 15, 1973.
Therefore, given that The Walt Disney Company and Disneyland both predate the first SeaWorld park by decades, Disney is older than SeaWorld.
