Stay after 15 Jul finally posted... But for stay close enough to 18 Aug cutoff day (like in my case, checked out on 17 Aug) they calculated using the new chart... which may or may not give you more points v.s. Starpoints x3 under the old system… But they forgot to post my 500 Pt welcome gift Starpoints / 1000 points...
Also for missing nights seems Marriott has removed the 2nd room night from my night count for 2018 i.e. one night even you've 2 or 3 rooms booked... Waiting for Marriott representative to confirm if this is the case...
