Even though my English isn't the best, the tour was a great experience thanks to Song, and hopefully he stays the way he is. Song, have fun in Thailand.

I went on the 18 day Thailand intro and had the trip of a lifetime! Everything from even before we arrived was very organised which led to a completely stress free trip. Our group leader Zoe was amazing, bringing such positive vibes from day 1, and provided complete support throughout the trip and for onward travel. Our local guide Aei-ki was fantastic and provided cultural knowledge as we went round. Would highly recommend Intro travel and this amazing country!
