I truly couldn?t have asked for a better trip!! My group was warm and friendly, our CEO Sony was intentional about supporting as many locals as possible with our visit, and it was a great mix of optional and included activities. The flexibility of doing what I wanted while also combining with the safety of having a group of other foreigners balanced out nicely. The price point was another great factor. I?d happily tour with G Adventures again!
