Starting February 26, 2026, you’ll be able to apply a Marriott gift card directly in the Marriott Bonvoy app.
I’ve never ever used a Marriott gift card, but it seems the old process was to get the front desk to try processing it toward your stay, and after 2/26/26, you’ll be able to apply it yourself in the Marriott app.
