'I think that's really illustrated by the creation of the MGM Collection with Marriott Bonvoy. It's not just a traditional franchise agreement,' Marriott CEO Anthony Capuano told TPG during a press conference Monday. Bookings for these 17 resorts will be accessible via Marriott's website and the Marriott Bonvoy mobile app, as well as MGM Resorts' booking channels. The Marriott and MGM tie-up begins in October with the creation of a new platform - the MGM Collection with Marriott Bonvoy - for some of the more than 40,000 MGM-affiliated hotel rooms across Las Vegas and other U.S.

The announcement comes less than a week after Hyatt and MGM announced their strategic partnership will end in September. On Monday morning, Marriott and MGM Resorts International announced a 20-year licensing and loyalty marketing agreement across 17 MGM-branded casino resorts in the U.S.

Hyatt's loss is Marriott's gain when it comes to Sin City.
