Arrival day is a cascade of decisions. Immigration → customs → SIM card → transport card → currency → train → luggage → check-in. This checklist walks you through each one in the order you’ll actually face them. No fluff — just the sequence and where to find the details.
Two things to know before we get into it: Google Maps doesn’t give walking or driving directions in Korea — download Naver Map or KakaoMap before you land. And if you’re taking the Airport Railroad, the AREX Express train does not stop at Hongdae. It goes straight to Seoul Station. You want the All-Stop train.

Step 4 — Arrive at Hongik Univ. Station, store your bags first
Check-in is usually 15:00–16:00. If you landed in the morning, the first thing you do is put the bags down.
