We did an excellent tour with Vincent, and I would highly recommend going with him. At first, it was a little stressful when we realized that we were leaving much earlier in the morning than we expected. (We were mostly worried about getting our 18-year-old up.) However, Vincent said that we needed to be early as you have to transfer to another bus with many tour groups. And we were able to get the first bus, and it also really helped to go early in the heat. So trust that Vincent knows what he's doing! The tunnel and later hike were interesting, but I appreciated Vincent's narration and storytelling at the DMZ the most. He was very moving talking about the war, and we watched the program on reunification that he recommended when we returned home. My husband is a Korean adoptee, and this was the first time he had returned to Korea. So the stories of people getting separted from their families particularly resonated with us. I'm a little late posting a review, but would highly recommend this tour with Vincent.
