AREX, T-money, метро, Naver Map
Google Maps transit слабый — Naver/Kakao обязательны.
Практика
- AREX Express ICN → Seoul Station 43 min; All-stop Cheongna cheaper longer.
- T-money card — CU/GS25 buy; subway bus taxi tap same card.
- Subway 05:30–00:00 — last train verify station; taxi night surcharge 00:00–04:00.
- Naver Map — walking transit accurate; Google wrong exit number common.
- Kakao T taxi — surge rain Fri eve; subway often faster Gangnam↔Hongdae.
- City tour bus — hop-on ok first day orientation not daily commute.
- Gyeongbokgung — Gwanghwamun Line 3; exit 5 palace gate 3 min.
- Luggage Seoul Station coin locker — large size sell-out 10:00 weekend.
