We spent 3 days with Vannak in Siem Reap, Cambodia in March. We had a tight schedule, so we opted for Vannak to pick us up from the airport and head straight to our first temple. Prior to meeting him, we arranged everything over email and he was very attentive and organized. Vannak was so flexible with the tour schedule. Our first full day, we woke up early and arrived at the main Angkor Wat temple to enjoy the sunrise. By 11am, we were tired and needed a break. Vannak knew of a local restaurant with hammocks outside, where we could relax and have lunch. This is just one example of why you should hire Vannak as your tour guide. As a native Cambodian and expert of Siem Reap, we didn't have to worry about anything. If we needed to go to the bathroom, he knew where they were located and how long it would take. We saw all the temples we wanted to see, learned history, and thoroughly enjoyed our visit. Vannak is such a nice guy and we really enjoyed his company. I noticed that Vannak knew all the other tour guides, and he was always friendly with a giant smile. You're going to spend a lot of time with your tour guide, so I recommend Vannak for his personality and attention to his tour groups. The Angkor Wat area is HUGE and I encourage having an expert to guide you through the area.
