The Free Shuttle Bus Service for foreign tourists between Seoul and Busan will get an extended run until the end of 2012.
Another service, to Jeonju, has had its capacity increased, but the free bus to Gyeongju will no longer be provided.
Services start Wednesday, following a short year-end break.
The schedule and drop-off points on the Busan route have changed. The route will run to and from Busan Lotte Hotel, but no longer go to Haeundae Paradise Hotel.
Buses leave Seoul from in front of Gwanghwamun Donghwa Duty-Free Shop at 8 a.m. and arrive at 2 p.m. The return journey leaves at 4 p.m. and gets to Seoul at 10 p.m.
Buses on the Jeonju route have been replaced with new 40-seat vehicles to support Visit Jeonbuk Year.
