Ripped off!
Been waiting for my fourth Q2 certificate and had to call HH CSR. Was informed that my stay that checked in on June 30th did not qualify for promo since I checked out on July 1st. T&C state promo runs through June 3Oth. I guess Marriott will start getting my 75+ stays a year over a petty issue. T&C should be more explicite on check in and check out dates.
PS. had 16 stays including the one in question plus one point stay. I would have used points on the June 30 th stay if I would have know it wouldn't count.
