I registered for the 2011 Q4 PICK OFFER ... I chose double points. In the last 45 days, I had 8 stays. Three of these stays didn't credit the offer bonus points. Sent an email inquiry to HHonors, only to discover that these three properties were not participating in the promo. The HHonors rep responding to my inquiry was quite professional in her message that I ****ed up, and offered some points to make up for my stupidity. So lesson learned, when you go to book a stay during a promo, double check the property exclusion list!
