Choosing Between AREX Express, All-Stop Train, Airport Limousine Bus & Taxi
If you are staying in Hongdae (Hongik Univ. Station), the AREX All-Stop Train (₩4,450–₩5,050) stops directly at Hongik Univ. Station in 46–54 minutes without any transfer—faster and cheaper than taking the non-stop AREX Express to Seoul Station and backtracking. If you are staying in Myeongdong, Gangnam, Insadong, or Jamsil with heavy suitcases, the Airport Limousine Bus (₩17,000–₩18,000, 6001/6002/6015/6009/6703) loads your bags underneath and drops you right in front of major hotels without subway stairs.
