I didn't realize that. For something that is going to be a permanent attraction for decades to come, it seems shortsighted that they shortened it so. They could have had something really great but due to this decision, it's fairly "meh".The size of the land it sits on isn't the problem. It was planned to be longer in the exact same confines it currently sits in. The problem, of course, was money and how they didn't want to spend too much of it. This picture has gone around the forum many times. It shows how long the ride was supposed to be compared to how it turned out.
It's a pretty ride, you just come off thinking, "That was it?" You don't get that on Big Thunder, Space Mountain, or Splash Mountain. You don't get that feeling on Everest or Rock n Rollercoaster. Even Little Mermaid, which isn't great, doesn't leave you with the "that was it?"-feeling.
