Okay, I have ridden the Hong Kong Space Mountain and the Anaheim Space Mountain rides. They are exactly the same except for:
1. The HK SM load area is on the ground level immediately once you enter the building. There is NO interior que (maybe 10 feet) and no build up.
2. At the top of the Anaheim first lift hill as you turn 180deg to head to the second small lift hill, the Anaheim ride used to have the Fedex satelite. Now it is dark. The HK ride has 3 asteroids there and they are illuminated and there is a projector mounted in one and is used to project images. I have ridden the Anaheim SM and if you look back (as you are heading to the small 2nd lift hill) at where the Fedex Satelite was you can make out the asteroids.
I wonder why Anaheim doesn't use the same effect as HK? They installed the asteroids but decided not to illumiate them?
