The Cosmopolitan of Las Vegas hotel-casino is turning to Marriott International Inc. for customers.

The under-construction resort on Wednesday said it has sealed a distribution agreement with Marriott to be part of its Autograph Collection, a set of independent upscale hotels the franchiser launched last year.

The partnership gives the nearly 3,000-room Cosmopolitan access to Marriott's vast customer database, and gives loyal Marriott customers their first option to stay in the middle of the Las Vegas Strip and win rewards points.

Cosmopolitan officials say it will be the largest resort in the Autograph Collection and its only property with gambling.
