Hilton has its own dedicated website for featuring hotels and deals available in the Asia-Pacific region.
This is just a skin as you make the reservation on main Hilton website and earn points/stay credits.
You can access the Asia-Pacific website here.
The website is further divided to five regions:
Australia, New Zealand & South Pacific
China, Hong Kong & Macau
Japan, Korea & Guam
Maldives, India & Sri Lanka
Hilton has really been pushing sales and promoting properties in the Asia-Pacific region that makes sense considering the population that is increasingly becoming middle class and thus more eager to travel.
