I have never negotiated the redemption rate down, but I have on a couple of occasions gotten a hotel to give me a "promotion"for staying a lot of weeks. My best deal was 5K for stays of 1-3 nights and 10K for stays of 4 nights or more at a Residence Inn, which helped negate the measly 5 pts/$ earning rate. I think I ran with that deal for almost 6-7 months before the individual left and the next person in her place refused to honor the agreement.
