Visit-prep decision table
| Problem | Best first check | Backup habit |
|---|---|---|
| Getting from airport to hotel | Destination, arrival time, luggage, last train/bus | Save hotel name/address in Korean and English |
| Using maps | Naver Map/KakaoMap availability and Korean place names | Keep a screenshot of your address and nearest station exit |
| Paying in Korea | Foreign card acceptance and cash need | Carry a small cash buffer and know one ATM option |
| Riding transit | Transit card top-up method and transfer rules | Use route apps and verify the final train/bus direction |
Most common visitor mistakes

- Arriving with only one payment method and no cash backup.
- Buying a data-only eSIM without understanding Korean phone-number limits.
- Ignoring last train/bus timing after a late airport arrival.
