Four Seasons has set up camp (literally) in Thailand's mysterious Golden Triangle (didn't this used to be scary, opium-producing backcountry?) It seems the hotelier is jumping on the "rustic luxury" bandwagon, catering to a crowd that yearns for adventure, yet can't do without the spa touch of Four Seasons. Thus you can mount an elephant, raft down the Mekong, and meet the local hill tribes-- and return at night to one of 15 Four Seasons tents, with hand-hammered copper bathtubs (imagine hauling that into the wilderness on the back of some beast-of-burden), down pillows and supersized robes, and wifi access. Yep, you heard that right. A riverbank tent with wifi and multi-line phones. Other swank services include five-course dining, spa, and free-form pool.
