Yes, there is a "secret" invitation-only tier above Ambassador Elite known as Marriott Cobalt status. This status is so exclusive that it is not listed on the Marriott Bonvoy website and cannot be earned through nights or spending alone. It is typically reserved for high-profile individuals, major corporate executives, or those with deep personal connections to Marriott's top leadership. Membership must be nominated by a Marriott employee and approved by the CEO. Cobalt members receive extraordinary perks, such as personalized greetings from the General Manager at every stay, guaranteed best-room upgrades, and exclusive experiences at luxury brands like The Ritz-Carlton and St. Regis, including complimentary lounge access.
