I currently have a case open with Marriott Marriott Bonvoy Customer Support for a stay from Feb. 24 to 25 that did not post the additional 2,500 bonus points.
The T&Cs contradict each other with "Earn on stays from February 25 through May 10" and "The promotion earning period is for eligible paid stays completed between 12:00am on February 25, 2026, and 11:59pm on May 10, 2026," which seems to indicate that I should be eligible as I checked out after 12:00am on February 25, 2026.
