Double Take: check the breakdown of your points earned!
I just checked out of the Sheraton in London. I should have received about 2700 base points. However, for some reason I was awarded 1600 base points, 1200 elite points (75% on top of base) and a mysterious 2600 “extra points”. The total amount of points may have been correct, but since they only gave me 1600 base points, I also only received the double take promotion based on those 1600 points.
