Me and my friends will arrive in Gimhae International Airport (Busan) at 10:15 in the evening. We're planning to go to Seoul immediately upon arrival.
From the Gimhae International Airport, what do we need to ride for us to reach Seoul.
How much we will pay for our transportation from busan to seoul?
Is KTX still available at that time? if no, Is there any alternative to reach seoul?
Thanks so much!
