From the description of Disney-MGM Studios’ Twilight Zone Tower Of Terror:
Board a phantom elevator, shoot up 13 stories and brace yourself for a thrilling plummet… but beware! The experience just got scarier. You rocket back up, only to plummet down yet again. You dare to ride once more, but wait! That’s not what happened before. That’s right, now the Tower is in control, so it’s never the same fear twice!
