I just called Hilton Honors to ask them a question and while waiting on hold was told they are currently updating their systems and to go to www.hhonors.com/2500 for 2,500 bonus points. Essentially, it seems like they are giving away these points due to long hold times. This promotion probably will not be up for too long, so register quickly.
When I finally got through to a Hilton Honors representative she saw that these 2,500 points have already been posted to my account. Pretty fast service in my opinion! Additionally, the representative informed me that the system upgrade would be a great benefit for the customer — they are doing away with issuing paper certificates, which means guests no longer have to print out and bring their certificate to the hotel. Instead HHonors will work directly with the hotel to get the award issued to your stay.
UPDATE: This offer is no longer available. Congrats to all the folks that were able to jump on this quick 72 hour offer!
