This past week was my first trip to Siem Reap. I really loved the town and enjoyed Angkor Wat too. My family and I had the opportunity to go with Sak Saum, the organization we work with. The journey was long -- 8hrs on a bus and a bit warm, but the conversation and laughs were worth it. For several of the Cambodians that went, it was their first time and maybe their only opportunity to visit Angkor Wat. I know they soaked up every moment!
I don't know that it's the easiest trip to make with kids, so if you are going to primarily shoot photography, it's best you plan a trip with your photog buddy so you can focus on that, but I was able to enjoy all the pieces while getting some great shots.
