I completed a 3 night stay at the Westin Guadalajara on June 19th. When I checked my account on June 21st the points and nights along with the Double Elite promotion had posted. It may have been sooner, I didn't check prior to June 21st but the reservation fell off the the upcoming stays list the day after check-out. After the 3-day stay my nights jumped from 49 to 55.
