Do not stack tower and tower
One height at dusk. If you climbed N Seoul Tower, close in Myeongdong and see the Jamsil lake in daylight — do not also take Lotte World Tower. On a Banpo fountain night, stay by the river. Do not climb a second tower. Yeouido is the west river: it can follow a Hongdae day, not a Gyeongbokgung day. The tethered balloon is only an add-on at Yeouido, not a second viewpoint. Bukhansan is not on this map. In rain, do not go up. Use the Seoul Museum of Art, or the indoor stop on the axis you already chose. After a fountain night, walk one stretch of river and go back. Do not buy a tower ticket on top. Two towers at dusk are not clearer than one riverbank.
