Newbie question here: How long does it take points and the night credit to show up on your Marriott account overview page after staying a night and checking out? Is it 24 hours after checkout? Thanks.
If you mean how long does it take for your credit to show up in Marriott Rewards, I have never, ever had it happen in 24 hours.
It depends on many factors, but typically *within the US* you might expect 48 hours to two weeks. Some of that depends on the property itself and handling the folio correctly on their end, and other mysterious arcana never to be revealed.
If nothing shows for 10 days, use the link on the page and inquire or call in.
