On Tiptoe to Reach Elevator Buttons Hotels like to throw around superlatives. And when they do, it is often in categories - customer service, hypoallergenic bedding, size of indoor gym - that matter to guests. But lately, a few hotels have fixated on a factor that isn't usually mentioned in TripAdvisor reviews: height. For vertigo-risking travelers keeping score on which hotel has the most soaring views, there is a new leader - the JW Marriott Marquis Dubai, top right, whose 1,164 feet make it the world's tallest dedicated hotel, according to the Council on Tall Buildings and Urban Habitat. Dubai, home to Burj Khalifa, the tallest building in the world, knows a thing or two about skyscrapers. The hotel, which officially opened Feb. 27, has 804 rooms on 72 stories, and will soon share its record with an identical tower that the hotelier is opening nearby by the end of this year. Still, you can get a hotel room on a higher floor in Hong Kong. The Ritz-Carlton there, bottom right, which opened in 2011 with fanfare proclaiming that it is the world's highest hotel, retains that title. It is lodged on the 102nd to 118th floors (which tops out at roughly 1,600 feet) of the International Commerce Center, which is the city's tallest building. The record may be settled, but the question of whether height is worth bragging about is still unresolved.
