Thank you to our tour guide Jan and driver Leap for their hard work on the day trip. Both were very thoughtful and explained things in great detail. Leap kept providing bottled water and tissues. Jan was very knowledgeable about Cambodian history, and we learned a lot from her explanations. She also remembered everyone's names, which was a big plus. 👍
