Just finished a tour of Sea World with my niece who works there part time.  I was surprised at the $92 entry fee per adult.  Adding in Disney World, and Epcot, a Florida vacation could cost several thousand dollars for the family of four flying in from the cold.  It is clearly directed to family fun and entertainment for the kids, kind of like a giant water circus…..  Sea World also does many injured animal rescues each year.  From my point of view, it was hard to imagine not just the initial expense of building the very special water facilities, but the ongoing maintenance and upkeep required.
