The new Marriott-MGM partnership is finally live.

MGM Resorts announced its switch to the Marriott Bonvoy loyalty program back in July 2023 after dropping World of Hyatt. Eight months later, MGM properties are now available to book through the Marriott Bonvoy reservations system, meaning members can earn or redeem points for stays.

This is a welcome addition for Marriott Bonvoy members headed to the Las Vegas Strip. Previously, The Cosmopolitan of Las Vegas was one of the few Marriott options on the Strip; with the addition of the MGM portfolio, there are nearly 10 properties.

Not all is lost for Hyatt members and the once-hefty Las Vegas Hyatt portfolio, though.
