I truly enjoyed my experience with GAdventures. The SouthEast Asia encompassed tour was a great way to see the highlights of 4 different countries. It was a great opportunity to truly experience each culture and give back to the communities. The tour leader really makes the experience as positive as it was. It wouldn’t be the same without Chen!
