Hilton has now launched their Any Weekend Anywhere sale for 2013. The booking window is from November 19 to January 31, 2013 (until February 14 in Asia) for stays between November 22 and December 31, 2013. You can access the Hilton’s very sparse web page for this sale here.

The discount and booking window is dependent of the region in question:
Europe, Middle East and Africa: Book from November 19, 2012 to January 31, 2013, for stays from November 22, 2012 to December 31, 2013.
Asia Pacific, Australia and China: Book from November 19, 2012 to February 14, 2013, for stays from November 27, 2012 to December 31, 2013.
Americas: Book through January 31, 2013, for stays from December 13, 2012 to December 31, 2013.
Discount by region:
Europe: 20% to 40%
Middle East & Africa: 33% to 40%
Asia Pacific: 20% to 25%
North & South America: 15% discount
Please note that all these rates are prepaid, non-cancellable, and non-changeable. Some hotels may require minimum of 2 night stay, at some hotels this discount plan is available 7 days a week,
Double Stay Credit for Hilton HHonors members
This is an interesting twist on a Hilton HHonors promotion that I have not seen before. You will receive a double stay credit for a stay booked under this offer that is at least 2 days.
Note that reservations booked under this offer may not be eligible for promotions that Hilton has in 2013.
Here are four examples booking using this sale compared to other publicly available offers:


At the Conrad Bali you are better off by booking the “Corporate Benefits Employee Offer”.

For Hilton Abu Dhabi this Any Weekend sale returned the best price. Other discount options either didn’t work or couldn’t beat the price.

The situation is same with the Hilton Berlin.

DoubleTree Los Angeles downtown had lower advance purchase rate and the MVP rate than this Any Weekend Anywhere offer.
Conclusion
The discount for properties in the North and South America is only 15% under this offer and that should be easily beaten by AAA, MVP, or even the Little League offer. For the Los Angeles properties searching through the Hilton’s sale page for this promotion didn’t return any rates. You could pull them up using the regular search, however.
This offer returned good rates for the property in Berlin and Abu Dhabi that I couldn’t beat using the other offers. The corporate benefits employee offer should work in both regions and the public employee offer in Europe, but they didn’t return attractive rates or rates at all for these two properties.
The Conrad Bali, wonderful hotel btw, had better rate using the “Corporate Benefits Employee Offer”.
You should always check all the rates and don’t trust that any of these “sales” offer the best prices all the time. Do your homework and compare prices against advance purchase rates, MVP, Corporate Benefits Employee Offer, Little League offer, and Public Employee offer.
If you have Hilton Gold or Diamond status, paying for a breakfast rate makes no sense as it is included based on the status. There have been several offers for Gold status through MVP, Visa Infinite, and airline related offers.
