Korean itineraries fail in predictable ways: a palace visit planned for its closing day, a tomb park reached after last entry, a second city added without counting the time to its station. These routes are built around published opening hours and fares, with the travel between stops written into each day.
The KTX does most of the work. It turns a second and third city into a morning's travel rather than a lost day, which is why these routes move more than a first look at the map suggests.
