This trip was a real eye opener into a very different way of life. It was very educational. We enjoyed the perspective of the local people when it came to past issues i.e, the war in Vietnam, the genocide in Cambodia. The group size was wonderful and we got to know each other very well.

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!

We have just come back from 2 incredible weeks in Vietnam and Cambodia, all arranged by the travel company. We had an incredibly memorable holiday and can’t thank Chloe enough for arranging such an interesting trip and also organising everything so perfectly. Our guides were all fantastic. We learnt so much more about how incredible Vietnam is thanks to all the information and personal experiences they shared. Our travel expert booked us into some lovely hotels and all of our transport arrangements worked perfectly. Highly recommended
