It was our first tour during the trip to Cambodia and Thailand. In retrospect, I have to say that Mr Siep Hour (alas, I am sure I am wrong with the spelling of his name) was the best tour guide during our entire trip. His command of English was the best and also his knowledge of Cambodian culture, history and customs was really impressive. We had informative and thoroughly pleasant conversations with him about Angkor Wat but also many other topics. He also has a great sense of humor and was taking our pictures from best possible angles. Needless to say, the organization was seamless, the guide and driver were on time, everything went according to a plan. We have seen and learned so much. Highly recommend!
The sights were obviously amazing...but the best part was having an expert tell us everything about the temples and sights we were visiting. Our guide was very outgoing and friendly. He answered questions and was a great photographer for us as well. It was also nice having a personal driver from place to place. There wouldn't have been any way we would have seen as much as we did in the amount of time our private tour took on our own. Hands down this was worth the money.
Our tour was private and I would suggest if you can afford it to do it this way. Our guide was wonderful, pointing out interesting facts and keeping the children amused. The temples we saw were awesome, with the children's favourite being the "Tomb Raider" Temple with its fantastic tree roots.
