Far away from the real sea? You are aware that SeaWorld Orlando is about 40 miles from the Atlantic and 60 from the Gulf of Mexico, right?
And they are particularly known for saving and rehabilitating Manatees in Florida that have been struck by boats. Most of the time, those manatees otherwise would die.
But if you're going to boycott SeaWorld, you'll also have to boycott Epcot and Animal Kingdom.
