Las Vegas hotel-casino, the Cosmopolitan, has announced a deal with Marriott Hotels which will give it access to the group’s massive database of customers. The new hotel, which is still under construction, will become part of Marriott’s Autograph Collection, a group of high end, independent hotels.

When completed, the Cosmopolitan will provide visitors to Las Vegas with nearly 3,000 rooms and is the only member of the Autograph Collection to provide on-site gambling options. Chief executive of the Cosmopolitan, John Unwin, said the deal with Marriott would give the hotel direct marketing access to customers of a range of brands including Marriott, Ritz-Carlton and Renaissance.

Marriott International’s chief executive, JW Marriott, said the deal would mean those customers who travelled to Las Vegas and did not book into a Marriott hotel would now have the option of booking into a Marriott affiliate.

Arne Sorenson, chief operating officer at Unwin, Marriott and Marriott International would not comment on the precise details of the deal but confirmed that Marriott would be receiving a percentage of the hotels revenue. This is typically between five and six percent of the revenue earned on each room, however the rate can vary, according to Sorenson. He also confirmed that Marriott would not be taking any the Cosmopolitan’s gambling revenue.

The Cosmopolitan has cost $3.9 billion and will have a gambling floor roughly 100,000-square-foot in size. It is owned by Deutsche Bank and plans to open its doors on 15 December even though around a third of its rooms will not be completed until after this date.
