Vegas Dream Projects and Failed Renderings. Found this through Wikipedia’s list of proposed Las Vegas casinos that never opened. Here’s the only one that matters:
One of the concepts for the large property directly across I-15 from the Mandalay Bay was the WWF, which would probably draw a rather rough crowd. The chances that this will be built are slim indeed.
Maybe not the best idea, but certainly the best computer rendering. There’s also a proposal for another Stratosphere ride that would basically be a single coaster drop from near the top of the tower. It would have been 800 feet high. Being conservative and estimating the actual drop would be 700 feet, that’s still about 300 feet higher than the current record holder Kingda Ka. And it’s 550 feet higher than the tallest drop I’ve been on (Goliath at Six Flags Magic Mountain). Basically this ride would have been awesome.
