The problem is the speed of development. There is a general lack of capacity in the hotel sector. Couple this with a govt encouraged tourism and conference sector, and an endless stream of business and govt people trailing through looking for a piece of the pie, and accomm can be difficult to get. There is such a shortage of capacity that hotels are also full during summer.
At work, we are used to prices doubling overnight due to some conference in town, or to every hotel being full. This is a problem in UAE, Qatar, and Oman. Bit of a drag, but booking WELL ahead should secure a room at a regular price.
