The absolute highest tier in the Marriott Bonvoy loyalty program is Ambassador Elite. To achieve this prestigious status, a member must stay at least 100 qualifying nights in a calendar year and meet a significant annual spending requirement, which currently stands at $23,000 USD (excluding taxes and fees). This status offers all the benefits of the Titanium Elite tier—such as a 75% point bonus, 4:00 PM late checkout, and United MileagePlus Premier Silver status—but adds two exclusive "crown jewel" perks. The first is Ambassador Service, which assigns a dedicated personal concierge to the member to handle all booking requests and special preferences. The second is Your24, a unique benefit that allows the member to choose their own 24-hour check-in and check-out window (e.g., checking in at 9:00 PM and staying until 9:00 PM the next day). While there is a "Lifetime Platinum" and "Lifetime Titanium" status, Ambassador remains the only tier that must be requalified for every year through high-volume spending and stays.
