The JW Marriott's Marquis Dubai formally opened Feb. 26 after gaining the title of tallest hotel from Guinness World Records. At 355 meters (1,099 feet), the hotel would tower over skylines in most cities. But in Dubai, it sits in the shadow of its more than twice-as-high neighbor, the Burj Khalif, the world's tallest skyscraper at 828 meters (2,717 feet).
