We did the trip last year and our guide and driver were great. Not only is he very knowledgable at the history and culture, we really enjoyed being with him. We needed a break from the temples so we did an afternoon trip to a floating village, which was a real eye opener. I think that having a guide is really important, he pointed out things that we would have just passed by.
Our guide was Keo Seng and his email

Good Luck and have a great trip!
