We are on a SE Asia Viking cruise. When an excursion filled up with what we wanted to do, I looked for other options hence Tours by Locals. I contacted a guide but he was unable to help me but recommended Hung. He is charming and knowledgeable. We had some issues with our time but Hung was flexible and created a tour for the time we did have. A highlight was going to the 49th floor of the skyscraper-Sky Dock. He convinced us to try coffee even though it was passed our "curfew" for drinking coffee. Yum!
