I am trying to use my Partial Package 7 night certificate before March 3 expiration date. Unfortunately, I have received conflicting information from 3 Marriott agents. One agent said I can only book 1 night and then use 100k points for the other 6 nights. But this can only happen after I stay the one night. She could not tell me how I will get my 100k points. I am confused and frustrated. HELP!
