Flat
Yeouido is a flat half-day. From the Assembly to the park, enter IFC or The Hyundai, not both. Eat inside that one building, then go down to the river or stop. 63 Building only on a day with no other tower. Saetgang is the quiet stretch. Whether a boat runs follows that day's slot. This page does not print an unverified fare. Do not attach Gyeongbokgung, and do not climb Namsan. If you want the tethered balloon, add it only to this dusk. It is not a second tower. Enter IFC or The Hyundai, not both, and eat inside that one. The other building waits. Do not use the flat ground as a reason to shop both. When the river wind comes up, go back to the district where you sleep. If there is no boat slot that day, do not wait at the pier.
