Correct, and the fact that the water was causing horrible hard water stains on the Mini's.
The side of the trains did not have neon green lights when the ride opened.
From my understanding of some folks who opened the ride, the "stair bump" was installed, but amounted to nothing more than the feeling that you were rolling over a rough piece of track.
I.E. Imagine sitting on a vibrating cell phone. The "effect" didn't translate well.
The effect was installed through the audio system which never really was fully installed and eventually abandoned.
The fog in the tunnel was cool. But yeah, the whole thing was way too over-engineered and didn't have the visuals that everyone was promised.
Unfortunately the ride was never really 100% completed as marketed.
