Vietnam and Thailand We used Jason from Asia Highlights as our consultant. He was phenomenal! He mapped out every detail of our trip and listened to everything that we had to say to help make our trip spectacular. We loved every minute of our trip and I can’t thank Jason enough. He is an excellent resource and should be commended for his attention to detail! More Louisa, Feb 2025

Amazing trip to Thailand From start to finish, everything was smooth and stress-free. I truly appreciated the attention to detail and the effort put into making this trip unforgettable.

Northern Thailand with Jinny We had an absolutely wonderful time touring Chang Mai and Chang Rai in Northern Thailand with Jinny as our guide. Jinny was not only incredibly kind and thoughtful but also went above and beyond to make our experience memorable. Her deep knowledge of the area, combined with her personal connection to Northern Thailand—having grown up in a nearby town—added a special and authentic touch to the tour. More Katie, Jan 2025
