I used Mike, whom I thought was good, we had excellent trips to Kanchanburi, and Ampahwah, he drove which was helpful. Not as lot of local knowledge needed. I also used a Chinese guy, Andy, who was studying law. Very good looking, but not available for sex! Sounds on food. Bright, good English, but when we went to Ayutthaya he knew next to nothing, unlike Mac! The distinction, according to Moses, is whether they are listed as Companion, or guide. Companion is not licenced, whereas a guide is. This is not entirely clear from the website. Andy was Companion, Mac was a guide.
