Next month I will be flying into Incheon then I have to get the bus to Daegu. My flight arrives 8.10 in the morning. Where do I catch the bus from and is it easy to find? How often do they go? Where do I pay and do they take credit cards? Do they stop for toilet brakes? Should I buy some food before I get on the bus? Does it just go to Daegu or does it go on further? How will I know I've arrived, is it clear? Sorry so many questions but it's my first visit and feeling a bit nervous. Thanks.
