    · April 1st, 2025
    The CEO, Pui was wonderful. Very kind and quite informative! She and I were both 33 and it was nice to have someone my age there. Most of the group were 18- early 20's, some sweet people but many in which I was happy to take time away from. I liked the accomadations, I did feel some pressure to participate in things that wern't my comfort zone. Which felt odd as, yes I may have paid for it upon booking, but to me as I paid for the tour I should have the choice in if I want to participate. All in all, I love forward to my next tour!

    I had an excellent time, and our CEO Channy was one of the best guides I have ever had. Overall, I think the itinerary was effective. However, our outstanding CEO made this tour stand out against all the other tours I have taken in recent years. In addition to being personable, Channy never hesitated to give us the 'inside scoop'. His attentiveness not only kept us safe but made the trip much more enjoyable over all. I look forward to my next G Adventures tour with him.
