Hotel Abraj Kudai is similar to a castle and has a ring of 12 towers that split 45 skyscrapers. At the top of the central tower, this hotel is the largest dome in the world. There are 5 hippies around this dome. Low oil prices could force the deadline to be pushed to 2018. By the time it does open the Abraj Kudai will overtake the current world’s largest hotel, The First World Hotel in Malaysia. There are 7,351 rooms in this giant property, which includes an indoor theme park.
