I'll be there Sunday and Monday. I don't have internet at home, so just give me a call/text (010-8505-2982).
The bus from Jinan to Maisan goes at 9:20, 1:50, and 4:50. A taxi costs 10,000 won. If you want to stay in Jeonju (40 minutes from Jinan) on Saturday or Sunday, you can stay in my apartment! Everyone else is welcome too
