Convenient way to go from Seoul to Busan. Bus is cozy, chair got USB charge for phone, tray for food, curtain to provide privacy. The only issue is when I get down the subway, the indication to the bus stop is not clear. There are two opposite directions for different line, but the line name not matching the destination name either, difficult to find out which direction to go, and eventually I pick a wrong direction, lucky I got enough time to go back. Suggest Klook add the same to their guidance, Klook did show the platform number, but that was for later stage.
