Rock n Roller Coaster. My favorite of the rides at Walt Disney World is arguably the most thrill-inducing ride in the parks. The Rock n Roller Coaster is a dark ride from 0 to 57 mph in mere seconds.

The ride takes you on a slow-moving trip through a haunted house and, as far as Walt Disney World rides go, can be scary. Despite opening in 1971, it's got plenty of modern bits to wow guests with.
