I for one think that all us Marriott Rewards users are smart. I did not sense any trickery or insults regarding the change. It is what it is. I am sticking with Marriott because I feel no other company offers a better program.
My only concern is that I have booked a trip for May '09 requiring "Stay Anytime Minutes" and the rules penalize me and don't allow me to re-reserve and use less points.
