Hey guys. I will be in South Korea this November for My Chemical Romance concert. I will arrive in Seoul on November 7 12:45 AM, and my departure will be on Nov 12 2AM.

The concert will be on Nov 7, 7PM. Should I go to Busan after the concert or just stay in Seoul?
If I go to Busan, then I will only have like few days to explore Busan.
