The key to six days across two cities is fewer luggage moves. Compare arriving in Seoul and leaving from Busan. If you already hold return flights from Seoul, reserve a separate return transfer and adapt the final day.
Day 1: arrive and settle in Seoul
Handle airport transport, hotel and dinner. Plan around the actual airport and terminal rather than treating Incheon and Gimpo as interchangeable. Keep your hotel address and intercity booking available offline.
Day 2: Jongno, a palace and art
Choose one palace, then focus on Anguk, Insadong or MMCA. Let a specific exhibition’s dates and booking rules determine the order. Swap with the Seongsu day if the palace is closed.
Day 3: choose Seongsu or Hongdae
Pick Seongsu for shops and coffee, or Hongdae with Yeonnam for a neighbourhood walk. Pack after dinner instead of following a late shopping marathon with an early train.
Day 4: check out → KTX → Busan
Use KORAIL to check stations, train and seats before arranging checkout. Include hotel-to-station travel, platforms and the onward transfer in Busan. Leave the afternoon for check-in and one nearby walk.
Day 5: one Busan theme day
Choose Haeundae and Cheongsapo in suitable weather, or Gamcheon and Nampo for hillside lanes and markets. Do not force both routes into one day. ARTE on Yeongdo is an indoor alternative, subject to admission.
Day 6: work backwards from your departure airport
For a Busan departure, allow time for luggage collection and airport transport. For a Seoul departure, add the intercity and airport legs and consider returning the night before. A tight last-connection plan provides little room for disruption.

Is a second city worth the moving day?
Six days and five nights are not six full sightseeing days. Separate arrival, departure and the cross-city move before choosing attractions. Ask each traveller for one reason to visit each city. If the second city is only being added because it looks close on a map, compare the plan with an extra two nights in one base.
Compare the flight pattern first
With Seoul arrival and Busan departure, keep moving in one direction. With a Seoul return flight, decide when to come back before adding Busan activities. If flights are not booked, include the fare difference, airport transfers and second rail journey in the comparison. Use actual quotes for the date rather than assumed prices.
Count from room to room
A moving day includes packing, check-out, travel to the station, luggage retrieval, finding the platform, the train journey and reaching the next accommodation. Allow time for food and lifts where needed. Keep the afternoon light and avoid putting a time-sensitive prepaid event immediately after the train.
Keep the choices deliberate
With only two full Seoul days, choose one palace theme and one neighbourhood theme. With one full Busan day, choose the coast or the old-city area. In rain, select a checked indoor option in the area where you already are. Budget only the extra costs created by the second city: rail, station transfers, accommodation-change costs and any flight difference. These are planning suggestions; confirm services, stations and seats with KORAIL.
