Choosing at Seoul Station or Myeongdong
Seoul Station has different stops by route. For 6001, Exit 3 and bay 3 at the bus transfer center are separate places. Myeongdong Station and Lotte Hotel/ibis Myeongdong are different stops too. Match your route’s stop ID to the map, not just a station or hotel name.
Choosing around Gangnam or COEX
6009 at Shinbundang Gangnam and 6020 at Gangnam Exit 12 use different stops. Around COEX, distinguish the City Airport Terminal, Bongeunsa, Samseong and night-service drop-offs. Compare the exact entrance to your venue or lodging, and reselect the boarding point for your return trip.
When your stop has no confirmed time
Do not use the origin’s first or last bus as the departure at an intermediate stop. Look for your stop in the linked operator timetable or ask the operator. A date or seat missing from booking results does not by itself mean service at that stop has ended.
