My girlfriend will be staying in a Marriott for 6 weeks for a work training gig. I have no knowledge of how their rewards work as i am an avid Hilton/Holiday Inn stayer. Can someone please link me or give some advice as to how we can maximize the points during these 6 weeks. Thanks in advance!!!

Oh, i did register her for the free night for 2 paid night stays, limit 2 free nights offer.
