I got two fee nights offer (Sun-Thur) from Cosmo via Identity. I know for sure they don't know anything about my Marriott status. And I really haven't played a whole ton there. Just a little bit here and there of the course of several visits to the hotel. Never actually stayed here either. Not sure if I will get a chance to actually cash in on it, though. Going to Vegas Friday, but the offer is valid 6/22 - 6/31
