MGM Resorts International is officially partnered with Marriott International through a strategic multi-year collaboration known as the MGM Collection with Marriott Bonvoy. This partnership allows members of both loyalty programs to match tier statuses, transfer reward points bidirectionally, and book stays at numerous iconic MGM resort properties directly through Marriott reservation channels. Historically, MGM maintained a long-standing partnership with Hyatt, but that alliance concluded when MGM transitioned its primary loyalty integration framework entirely to Marriott Bonvoy, creating a massive new ecosystem for cross-brand hospitality rewards and guest benefits.
