Just received an email from HHonors for 2,500 bonus points for making a weekend booking. It specifically requires the bookings to be made during a specified 24 hr period. Also note that there is a max of 10k points from this promo and also requires you to go back into Facebook to submit your confirmation # from your completed stay to obtain the bonus. Although the rate is discounted, it also seems that the reservations is a non-refundable one as well. However, it seems like a nice little bonus if you were already going to make a weekend booking. In addition, there may be an opportunity to stack this on top of the other HHonors bonuses that are out there during the 1st quarter. Here's the language in the email: RSVP on Facebook now so you won't miss the Any Weekend, Anywhere Sale 24-Hour Bonus Event starting January 17, 2012, at 12pm ET. You can earn 2,500 Hilton HHonors™ Bonus Points and save up to 33% for stays during any weekend through 2012.* Simply book your Any Weekend, Anywhere Sale stay during the 24-Hour Bonus Event for any weekend night at any participating hotel or resort to get both the points and the savings.
