Hilton HHonors members can earn 1,000 points per night for weekend stays through Dec. 31, 2012. Register for the 1,000 Reasons promotion and earn 1,000 bonus points per night on Thursday, Friday, Saturday, Sunday and Monday nights at participating hotels and resorts worldwide. Members will earn the bonus points per night, not per stay, so members can earn up to 5,000 points per stay over an extended weekend. Not all hotels, however, are participating in the promotion and you can view a list of over 250 properties worldwide that have opted out of the promotion at the registration page, http://www.HHonors.com/1000Reasons. There is no limit to the number of points members can earn, and as long as you register for the promotion prior to checkout, you will earn the bonus points regardless of when the stay was booked.
