I just wanted to update/correct some of the info in the LP regarding traveling around Jeju from Seogwipo.
As the LP states, there is a bus station for Seogwipo and Jungmun at the World Cup Stadium, a few kilometres west of Seogwipo, however you only need to go there if you are traveling to the west part of the island.
If you are in Seogwipo and want to travel to Jeju City, Jungmun or the east part of the island, it's probably more convenient to go to the bus "station" (it's tiny) near Jungang Rotary (#34 on the Seogwipo map). Buses to Jungmun and Jeju City pull into the station and line up facing west.
If you want to go to the east island, there is a bus stop on the road just in front of the station a few metres from the Jeju City buses, same side of the road. The buses you want to catch will be heading towards the rotary.
