To add a little more detail, Marriott usually runs 3-4 open-to-all promotions per year (though there’s often a gap between them). The 2022 Q4 one ended a couple weeks ago (https://www.flyertalk.com/forum/marr...tml?styleid=24) and they have not announced anything yet for 2023 Q1.

Also, seemingly at random, Marriott will offer individual promos (ranging from extra points to free night certificates after so many stays to extra elite qualifying nights). As far as I can tell, there’s no discernible pattern to who gets what kind of offer or when.

All can be found in the “my promotions” page under your account
