We had a wonderful tour with Oliver (Unsuk J.), as arranged he picked us up from our hotel and we did the all-day DMZ tour before Oliver dropped us off at Incheon airport for our flight home. On the way to the DMZ Oliver explained some of the background to the Korean conflict and explained what would happen once we reached the DMZ and took the shuttle bus to the third tunnel, observatory etc. Oliver was a very knowledgeable guide and very helpful and his minivan was modern and comfortable, and our correspondence before the tour was helpful as we had to make some timing changes due to an alteration in our flight times. On the day, as there was some extra time before our flight after the main excursion Oliver also made an extra unscheduled stop to view the DMZ from a different location, which was very kind. Thank you Oliver, the tour rounded off our short trip to Korea very nicely. Neville and Lynne Hallam
