Saudi Arabia has laid out its ambition to build a hotel of such magnitude, allure and luxury, that travelers from the world over will come to see it. In Dubai, the emirate has the two Atlantis resorts, between them almost 2,000 rooms. In the US, historic hotels such as The Plaza sit in New York and mega-resorts fill the Las Vegas strip. But in Saudi a set of three boutique hotels will be the “global bucket list” destination of choice.
