now, for all you seoulites out there, how many of you can safely say that you know the number of times you can change buses without having to pay an additional fee?
The magic number here is 4! That excludes the bus that you originally took. However, do note that all transfers have to be made within 30mins. The allowed time for transfer increases to 1 hour after 9pm.
Just thought that I would share this little titbit with all you potential tourists/current residents out there!
