Checked out of Marriott Hongqiao in Shanghai on 6 Aug and the points still have not posted. The response from Marriott was that it takes 14 working days (almost 3 weeks!). This must make them the slowest program out there as far as speed of points posting is concerned. Last weekend's stay at Holiday Inn in BKK has posted 2 or 3 days ago. From my experience, Hyatt, Starwood and Hilton are all pretty quick.
