Building managers for the Excalibur had been on a schedule of repainting the building’s brightly colored castle turrets with polyurethane every three or four years – at tremendous cost – in order to keep them vibrant under the intense Nevada sun. Seemingly overnight, massive casinos and hotels sprung up along Las Vegas Boulevard, drawing visitors’ attention and increasing the pressure for existing businesses to stand out. The Excalibur was one of the first “theme” casinos on The Strip and ushered in a new era of extravagantly designed buildings for Las Vegas after it was completed in 1990. Las Vegas is known around the world for its image of vitality and excitement, but the Excalibur Hotel and Casino found out that living up to the expectation in a brutal desert environment is far from a sure thing.
