We did the two day trip with one night in a tree house. I can quite honestly say that this was one of the most wonderful experiences of our entire time in SE Asia. My wife wasn't very pro in advance due to a fear of heights but even she ended up absolutely loving the experience. Great guides, great accommodation (unlike anything ever stayed in before) and felt very safe the entire time. Cannot recommend this enough. Writing this quite late on as we visited Oct 11 but date don't go back that far, but still thinking about it. 2 years ago today!
