Travelers wanting to plug into the country's epic party scene would do well at these 17 hotels, where rooftop bars are local hot spots and where beach clubs become crazy late-night clubs. (Don't worry, Thailand's intricate temples and postcard-perfect beaches are excellent for restoring the Zen the next day.) Here are the top party hotels in Bangkok, Phuket, Patong, Koh Samui, Pattaya, Chiang Mai, and Koh Tao.
