Arrive ICN 6:45am. Depart same day GMP at 8:15pm.

A few quick questions.

1. Both flights on the same PNR (OZ>NH). Can I check bags through?

2. If not, I'm thinking to head to GMP first thing and check the bag there. Just a roller-board so walking a bit is not problem. Train or bus to GMP?

3. Would probably like to crash for a few hours and get a massage. Any recommendations on hotels or other options? (Nice facilities and convenient location are important. Doesn't need to be cheap).

4. Might catch up with a friend for lunch, but looking for something to do in the PM. Any suggestions?

5. Best way back to GMP in the evening? Taxi? Uber? Bus?
