What an amazing experience!! We worked with the tour agent for over a year to plan our vacation and it couldn’t have turned out more perfect! Tracey listened to all over our hopes and interests, and delivered an itinerary that ended up being a dream vacation! We spent 2 weeks exploring Vietnam, Cambodia and Thailand with our family of 5 and the guides we had in each city were wonderful, knowledgeable, and felt like our friends just showing us around their country. We will absolutely go through them again when we find time to explore more of Asia!

My wife and I truly enjoyed this incredible tour. The 3-star hotels exceeded our expectations, not only in comfort, but also in location, allowing us to easily explore local life. Every pickup was seamless. The tours themselves were well-organized and each experience was memorable. Honestly, our only regret is not having more time in each of these amazing places! A special thanks to our dedicated rep, Evelyn, who supported us throughout the trip. This was a 5/5 experience, and we’ll absolutely be recommending it to family, friends, and colleagues!

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.

Did this trip with my 20 year old son. Great father son bonding time experience. Would go back and do it again happily. You need to be pretty fit to get through the whole event. Definitely take factor 50 sun cream, gloves to keep your hands from burning, long sleeved tops and loose trousers to cycle in. It was 35 to 37 degrees when we went in early February. Guides were amazing, off road bicycles were great. The last two days in Cambodia were pretty arduous but the day cycling around Angkor Wat was an all time highlight of my life.
