And you thought your last penthouse suite offered a nice view. The newly-opened JW Marriott Marquis Hotel Dubai gives its city two world's tallest claims — one for the tallest building, and one for the tallest hotel. Standing at a height of over 1,150 feet, this massive building offers 684 guest rooms and 120 suites spread across 72 floors, no less than 16 bars and restaurants — including Vault, which sits on the 71st and 72nd floors. It also features a fitness center and health club, an on-site spa, spectacular views of the Persian Gulf, and nearby access to nearly any activity you could imagine, including golf, scuba diving, rock climbing, bowling, horseback riding, and, yes, even snow skiing — this isDubai, after all.
