A record-breaking hotel in Abu Dhabi will finally open its doors December 21, after a series of delays.The Hyatt Capital Gate hotel, which offers 189 five-star rooms, leans a record-breaking 18 degrees -- more than four times that of Italy\'s famed Leaning Tower of Pisa, which is angled at just under four degrees.The striking style of the building, which is part of the Abu Dhabi National Exhibition Centre, earned it a place among Guinness World Records last year, despite a two-year delay in the handover.Now, guests will be able to sleep in guest rooms that hover over nothing but air, with the Hyatt occupying floors 18-33 of the structure -- each floor protrudes  by between 300mm to 1400mm.Among the features is the Rayana Spa, a \'sky-spa\' perched on the 19th floor offering \"a refreshingly elevated oasis experience\" along with a suspended outdoor pool and whirlpool. Restaurant options include eastern Mediterranean cuisine at the 18? restaurant, a chic bar called Privé, the \"residential-style\" Lounge, a pool bar and the Lobby Café.The Hyatt Capital Gate is the second landmark property to open its doors in Abu Dhabi recently, following the debut of Jumeirah at Etihad Towers November 1.The first Abu Dhabi property for Dubai-based Jumeirah, the 382-room hotel offers 12 restaurants, bars and lounges and showcases photography from the private collection of local royal Sheikh Suroor bin Mohammed Al Nahyan.
