Hilton has several websites outside of Hilton.com featuring region specific sales or weekend deals. For those that travel in the Asia Pacific region, should check out the Asia Pacific sales website.
Although the website is Hiltonhoteldeals.com, it is merely used as a skin and the actual booking is done on Hilton.com. The presentation of hotels and region specific deals on this site is better, however.
Here are the current sales:
Australia, New Zealand & South Pacific
Mainland China, Hong Kong & Macau
Japan, Korea & Guam
South East Asia
Maldives, India & Sri Lanka
Conclusion
I really like the layout and the presentation of the hotels and sales on this Hilton website that is entirely dedicated to their Asia Pacific hotels. Worth checking out every once in a while.
