Hi! I'm flying to Seoul this Sunday at 2:30 am from capital airport.

I know that the last train from Sanyuanqiao departs at 22:34, so I'm gonna have to wait a tad :P

Do you know if I will be able to exchange money at the airport (from Yuan to Won) at that time (around 23:00)?

If you have any other advice, please let me know! :) Thank you!!
