Does Marriott allow members to transfer points to other members?
Yes. Here's the appropriate section of the Marriott website.
Scroll down to the bottom where it says "Share your points" for details.
But bejacob to take this a step further, if I transfer 50K points from my MRI to another members MRI will I lose the 50K points from my Lifetime balance?
Yes. That's exactly what happens. If you transfer points, your lifetime (and current) balance will decrease while the recipient will see both numbers increase.
At least that's how it's supposed to work. I know some folks have been having trouble getting the points transferred in to count toward the LT numbers (see Point Sharing and LT Status as one example).
Interestingly the customer support rep said it will not reduce my LT points. Guess I have to wait and see!
