No, Marriott Bonvoy accounts are strictly for individual use, and the program terms and conditions prohibit two people from "sharing" or co-owning a single account. Each account must be registered in the name of one individual, and that person is the only one who can earn "Elite Night Credits" or "Points" for a stay. This is a common point of confusion for couples who want to pool their points toward a single goal. While you cannot share an account, Marriott provides a very flexible "Points Transfer" feature; any member can transfer up to 100,000 points per calendar year to another member's account, and a member can receive up to 500,000 points per year. This allows couples to maintain separate accounts but combine their wealth for a specific luxury booking. It is important to note that the name on the reservation must match the name on the Bonvoy account for the benefits (like free breakfast or room upgrades) to apply. If one spouse has "Titanium" status and the other has "Silver," the Titanium member must be the one staying in the room to receive the perks. Trying to "share" a login or use someone else's status when they are not present can lead to the account being audited or permanently closed for fraud.
