Its nice that your finally changing the way the rewards program is set up. But the big underlying issue is your peak times. Starwoods doesn't change the room point fee's just because the weather is warmer. I was an advid Marriott Reward cusomter for about 5 years than went to starwoods as the rewards are more vaulable. I would gladly change back, but when i can pretty much to the same islands, resorts etc, for less points, there by stretching my rewards out, why wouldn't I? Aruba most times costs almost 300k points for a week, other times its 125k estimated of course.
Please address the peak points and bring it into line with SPG.
