I've heard a lot of people online make the half-day park claim and several people in my own family aren't inclined to give it more time than that either. But I really think they are missing out.
It's true that if the only thing you care about is rides, then you're not going to occupy even half a day. But opening your eyes to all the things going on around you reveals so much to do.
It is one of, if not the most immersive theme park environments you can experience. The mix of shows, animals, education and rides put together gives loads of things to do. And the place is just gorgeous.
People who don't give it a chanced because they're so focused on, ride, ride ride, are missing out big time.
