The top spot on our list goes to Disney’s Expedition Everest. Walt Disney World in Florida made the 2011 Guinness World Records for most expensive roller coaster, a title which hasn’t yet been broken. It took over six years to design and construct the ride, the storyline of which features a yeti guarding the “forbidden mountain”. When it comes to height, speed and lengths – the coaster is remarkably average. What makes this ride special is that it can go both forward and back during a single ride, not to mention the extras and set designs are much more advanced than others of its kind.
