On Space Mountain, it's as if you're traveling through space at Mach speed, and it's all in the dark, so there are twinkling lights all around you as you hurl through dips and turns. It's basically a roller coaster in a pitch black room.
Talk about excitement. It takes you from 0-55 mph in FOUR seconds at the start (see picture at right). Sooooooo fun!
There are a couple of steep climbs, dips and 180 degree turns that had me screaming for joy, plus the highest drop of 120 feet. The ride lasts only 2.5 minutes, and I was so sorry when it ended.
This was the only part of the ride that felt slightly rough; the rest was smooth as air.
Of course, there are a hundred more things to do and see at Disneyland, but these were my faves!
