Days 1 to 3
The first three of five days do not collapse into one list. Day one is only Jongno: one deep palace at Gyeongbokgung, the Bukchon slope, dinner in Ikseon. Day two is only Myeongdong and Cheonggyecheon, with one meal at Namdaemun or Gwangjang. Day three is only Hongdae and Yeonnam. Mangwon is the west dinner, and it can reach the river at Yeouido. Do not open Gangnam. Each day closes on its own axis. Do not climb two towers at dusk. Each of the three days closes on its own meal: Ikseon, Gwangjang or Namdaemun, Mangwon. Do not use the evening to start tomorrow's axis early. Tonight's bed stays on this axis. Keep the three meals at Ikseon, Gwangjang or Namdaemun, and Mangwon. After you eat, go back to the hotel. Do not sit the table into the next district.
Days 4 and 5
Day four opens one south line. Garosu-gil as far as Dosan and Cheongdam, or the Seongsu warehouse lanes and then Seoul Forest, or the Jamsil lake and Lotte World Tower. Do not open all three, and do not pair them with another tower. Day five is rain or one Yongsan museum. In rain, pick one of COEX, DDP, Yongsan I'Park and Yeouido IFC, and set a leaving time. That day does not open a second night district. If day five is clear, it is still one Yongsan hall, or one stretch of the south line you did not walk. Do not collect all three south lines in one go. Keep the museum to one hall in Yongsan. If it is still raining, stay in the indoor place you already chose. When the leaving time comes, exit. Do not add a second mall to fill the day.
