From noon tomorrow EST through 11:59am Wednesday, if you book a weekend night with a Hilton brand property for a stay anytime this year, you can receive 2,500 bonus HHonors points upon completion of each stay up to a maximum 10,000 points for four stays.

This 24-hour event highlights the loyalty program’s “Any Weekend, Anywhere Sale,†where participating properties are offering up to 33% off weekend stays, which comprise at least one night on a Friday, Saturday or Sunday. Thursdays also qualify, but require a minimum two-night stay.

To get the bonus points, there’s a little more action required than many recent HHonors promotions. Here are the steps:

1. You have to book a stay either via their Facebook page, or through this web link.
2. Assuming you’ve done this between the 1/17/12 – 1/18/12, noon to noon EST parameters…
3. Return to the event’s Facebook page and enter your confirmation number along with your HHonors information.
4. Once you’ve successfully completed that stay by 12/30/12, expect to see 2,500 bonus points in your account in 4-6 weeks.

View the other terms and conditions for full details, but in a nutshell, you’re maxed out to earn this bonus four times for a total of 10,000 HHonors points. Also, the biggest “catch†is that the reservations you make under this promotion are totally nonrefundable. A 7-day advance purchase is additionally required.

It’s still a nice bonus if you already have expected, but not-yet-reserved stays, and even if you don’t book during the allocated 24-hour window for the bonus, the “Any Weekend, Anywhere†sale continues through January 31, 2012 via this web link.

I have oodles of upcoming weekend stays already booked at advance purchase rates, so unfortunately can’t change those for inclusion with this promotion. Alas, I planned too far in advance. Hope you can take advantage.
