Incheon or Gimpo: choose the right arrival route
Incheon International Airport, ICN, has Terminal 1 and Terminal 2. Save your flight terminal before choosing AREX or a booked airport bus. The AREX Express serves Seoul Station, while the all-stop service offers other connections including Hongik University. For Gimpo Airport, GMP, download the route from that airport instead. Keep your hotel’s Korean address and final entrance beside the booking before leaving arrivals.
Subway exits and four Seoul places
Save subway line numbers, travel direction and exit numbers before boarding. Naver Map or KakaoMap can help you look up Korean place names; keep the venue’s Korean address alongside the map pin. Download your next connection before underground sections, where signal can dip. For booking apps, check account requirements in advance: this data-only plan provides neither a Korean number nor Korean SMS identity verification.
- Myeongdong: save the hotel entrance and nearest exit rather than using the entire shopping district as a meeting point.
- Gyeongbokgung: download your booking or visit details and chosen entrance before arriving at the palace grounds.
- Hongdae: agree on an exact café doorway and Hongik University Station exit before meeting friends.
- Seongsu: keep the shop’s Korean name, building entrance and return route handy before exploring the café streets.
Seoul-specific tip: Seoul Station’s AREX, subway and mainline train areas use different access routes. Save the service named on your ticket and leave time for the interchange walk, especially with luggage.
For a Suwon outing, download the rail connection, final route to Hwaseong Fortress and return arrangements before leaving Seoul. Keep the meeting point beside your itinerary rather than relying on a broad fortress-area pin.
