You might also consider trading for Marriott Gift Checks. Gift checks work like cash at Marriott. Basically anything that lands on your bill can be covered by the gift check. For example: While vacationing in Florida, I purchased $1000 in Gift Checks (135K points). At the concierge desk, I was able to buy five 3-day passes to Disneyworld. Of course, I put this $835 charge on my bill, paid with my Gift checks making the tickets essentially free. Sweet!
