Wilai is an excellent guide I have never met before. She is very friendly and helpful. She has deep knowledge in Thai culture and history. The tour arrangement is very flexible especially the lunch. Wilai entertained our request to have Thai food lunch in lieu of buffet. The restaurant is near the Meikong River and facing the border of Burma and Laos. Wilai’s arrangement is wonderful and the food is also delicious. During our visit to long neck village, Wilai tell us the history of the ethnic minority very briefly. The driver is also very nice and helpful. It is an unforgettable tour. I strongly recommended Wilai to be your guide.
