Dubai needs 2.5 million more tourists a year to absorb its 60% increase in hotel rooms over the next five years, according to Deloitte.

The New York-based consultancy firm says Dubai has 50,000 hotel rooms and may struggle to maintain occupancy and rates because the city plans to add 30,000 more rooms.

Deloitte warns that even if half the planned hotel rooms are added it will be difficult for Dubai’s hotels to maintain occupancy and the city will need 12 million visitors from its current tally of 9.5 million, according to Bloomberg.

According to data from Dubai-based Kyriakidis, Dubai’s average hotel occupancy has fallen to 70% from 80% in 2007, while revenue per available room is estimated at $240, down from $300 in 2007.
