Pirates of the Caribbean has large drops in California which adds to the thrill level, in Florida it's just Small World with Pirates in it. Space Mountain are radically different rides. Just because they are both indoor roller coasters it doesn't make them the same ride. One is enjoyable, the other one hurts to ride. Disneyland Park also has 9 more rides than the Magic Kingdom. They are not the same thing. To me, Magic Kingdom is the worst of the 6 US Disney parks.
