Hilton is offering a new promotion starting February 1 and going through April 30, 2014. This is perfect timing as their current promotion ends January 31 so there is no lag in between promotions.
You will earn 1,000 HHonors Bonus Points for every night you stay at a participating Hilton hotel. And for every weekend stay of two or more nights you’ll earn an additional 5,000 bonus points (a weekend is defined as Thursday through Sunday night). Although the promotion states “earn up to 9,000 bonus points”, that means per weekend not total through the life of the promotion. There is no limit to the number of bonus points earned during the promotion period, however, you may only earn one 5,000 point bonus per qualifying weekend stay.
I personally would not stay at a Hilton hotel solely based on the promotion, but if you happen to find yourself staying there free points are always great.
