Siam Hut has amazingly cheap bungalows right on the beach of Koh Chang. The bungalows come air conditioned or with fans, they have private bathrooms and there's a big communal seaside deck off the Tree House restaurant. At night they light these lamps on the deck, the fire dancers dance on the beach and every full moon marks a huge party. Siam Hut is low key and a bit remote but easily accessed by walking or taxi.
