I recently stayed at the Washington Marriott at Metro Center in DC for 4 nights at the beginning of April. I waited the obligatory 10 days before reporting my missed stay and am now into my 6th day of waiting for credit for this day with the hotel bill submitted. I haven't experienced such a delay in credit for nights stay before. I prefer to stay at the new Marriott near the convention center on Mass Ave. The service there is incredible. I have no complaints for the Metro Center Marriott but I really want my points at $320 a night. I have stayed in Marriotts in other locations since this and have already received credit. Why is there a delay???
