The shape

NightsWhereWhy
1–4SeoulPalaces, markets, one day trip, one unscheduled day
5GyeongjuOn the way south, and a different kind of day entirely
6–7BusanCoast, markets, and a relaxed finish

Fly into Incheon, out of Gimhae in Busan if your airline allows it. One direction, no backtracking. The day-by-day is below.

Do not add Jeju
