The Abu Dhabi Tourism Authority said yesterday that Aldar Properties will commission seven hotels on Yas Island by November. The commissioning will be in time for the UAE capital hosting the final round of the 2009 Formula One Grand Prix during the month. The hotels - four 5 star properties, one 4 star and two 3 star - together will boost Abu Dhabi's accommodation inventory by 2,298 rooms and its food and beverage stock by 30 outlets, including 20 individual restaurants, the authority said.
