We are planning to go on this October. The plan is after arrive on Incheon Airport, we will directly go to Busan. We are hoping to catch KTX, but the problem is we will arrive at 22.30 while when I tried to check, last train to Busan is on 23.00. I'm quite sure it is impossible to take KTX.
Also, already for bus, last bus is around 22 also.
Is there any other way to reach Busan ?
Or should I just stay overnight on airport and try for first train?
If yes, would anybody share any advice of stay overnight on Incheon around that time?
Thanks a lot.
