| Airport bus 6001 / 6015 / 6701 | 6001/6015: KRW 17,000 adult / KRW 12,000 child. 6701: KRW 18,000 adult / KRW 12,000 child | Low if your hotel stop is genuinely close | You want fewer stairs, fewer platform changes, and less last-mile stress | Traffic can stretch the ride, especially at busy hours |
| AREX all-stop or express, then transfer | All-stop: KRW 4,750 from T1 / KRW 5,350 from T2. Express: KRW 18,100 from T1 / KRW 18,700 from T2 | Medium to high if you still need subway or sidewalk walking after Seoul Station | You value predictable rail time and the last segment is still easy | Myeongdong often adds one more transfer or short taxi after the train |
| Taxi or private transfer | Highest total cost; official designated international taxi uses Seoul flat-fare structure, private transfer varies by vehicle | Lowest | You want the least physical effort, especially late at night or with family | Price is hardest to justify for a solo traveler with light luggage |
