If you don't like shopping or eating or conversing with the locals stay inside. Probably the bestmaybe the only place to hang out during the day is Wat See Tarra Rahm. You can have an amazing Thai massage for 100 baht, but do tip generously, and a hot herbal body scrub for 50 baht. They also have yoga classes every weeknight from 5PM for an amazing 5 baht. Mondays and Tuesdays are taken by Kru Apple, probably the world's best yoga teacher, and definitely the world's most relaxing voice. You can also find Kru's Nid and Dang there. They run the town and Nid speaks good English if you're in desperate need of some translation or just a familiar language.
