Hotel giant Marriott International has made an agreement with Las Vegas’s newest hotel-casino, the Cosmopolitan, to share its database of customers in return for a percentage of room revenue. When it opens its doors in December this year, the Cosmopolitan will offer close to 3,000 rooms to its guests as well as a casino which will be 100,000-square-feet in size.

The deal means the Cosmopolitan will become a member of the exclusive Marriott Autograph Collection which is a group of up-market hotels which are independently owned but with an affiliation to Marriott. Commenting on the deal, Marriott’s chief executive, JW Marriott, said customers who did not choose to book a room in a Marriott in Las Vegas now had the opportunity to book into Marriott product.

John Unwin, chief executive of the Cosmopolitan, said the deal would give him access to a huge database of names of potential customers who he could market the Cosmopolitan to. He added that he would now have a position on the largest retail website in the world in terms of hotels.

According to Arne Sorenson, Marriott’s chief operating officer, the hotel group will not receive any revenue from the Cosmopolitan’s gambling operations but will take a percentage of the hotel’s room revenue. Sorenson explained this was typically around five percent.

Tourism analysts will be keeping a close eye on the Cosmopolitan when it opens as it is probably going to be the last big hotel-casino to be built in the city for the foreseeable future.
