I have had the worst experience with this promotion, indeed I get the 1000, but trying to get the 500 extra through Marriott has been an ordeal. I email and weeks go by, email again, they say I have to be elite, I ask them to read my email as I am Titanium. Still waiting. This has happened numerous times, and its like a standoff.
Eventually in the past, I received the accurate posting, but in all honesty, this could/should be a better system.
