Giorgio Armani's first hotel, due to open in Dubai's Burj Khalifa, will be delayed by more than a month, Bloomberg has cited sources with knowledge of the plan. The luxury hotel, occupying 10 floors of the world's tallest building, is now scheduled to open on April 22, according to sources. The hotel, designed by Armani himself, will include eight restaurants, a spa and a lounge, in addition to chocolate and flower shops.
