Asia is a favorite for business travelers today, focusing on Hong Kong, Shanghai, Tokyo, Osaka, and Singapore. But the leisure traveler will be amazed by the towering hills of karst terrain, the Great Wall of China, and the teetering limestone islands of Phuket, Thailand, and Vietnam. Enjoy Asian cultural festivals throughout the region, or trek as high as your dare in the Himalayas. Book great hotel rates to see India’s Taj Mahal.
