Hilton is offering up to 40% off on weekend reservations at most locations with 2,500 bonus points for every weekend booked through the end of 2013. The reservations have to be made by the 17th (tomorrow) at 11 a.m. and booked through their Facebook page to qualify for the 2,500 points.

If you miss the deadline to get the 2,500 bonus points, you could still get the 40% off and earn double points instead by booking by January 31.

Here’s how to get the points and the discount:

1. Enroll in the HHonors Program for free.
2. “Like” the Hilton HHonors Facebook page to book reservations.
3. Make your reservation.

Also, this deal is good for any of the different Hilton chains: Conrad Hotels & Resorts, DoubleTree by Hilton, Hilton Hotels & Resorts, and Waldorf Astoria, Hilton Garden Inn. Participating locations are throughout Europe, North + South America, Europe, Asia, Middle East and Africa.
