How long does it take for Marriott to credit nights to your account after credit from your Marriott Visa have been added to an account? It is now June and I have yet to see anything from the points added in March.
That is too long. I assume you are looking to get the additional night credit for spending $3000. Points usually show up within a few days of the statement date, but it takes a little longer to get the elite night credit (but not that long). Give Marriott Rewards customer service a call. They might refer you to Chase, but start with MR. They should be able to sort it out.
