2. Get off the bus at Daejeon Government Complex stop.

It takes about 2:30 hours to get to this stop.

It would be safe to ask the driver “Is this stop Jeng–Boo–Cheng–Sah?” or show the following, meaning “Is this Government Complex?”:

“여기가 대전 정부청사입니까?”

At the bus stop, either you meet your host at Hollys Coffee (usually), or take taxi to your hotel or KAIST.  Taxi is generally cheap in Korea and many taxi’s accept credit cards (watch “Card” sign). Tipping is not necessary.

Note 1. Occasionally, there is a short break (15 min) at a highway resting area before getting to Daejeon.
Note 2. Often, “Government Complex” is the 2nd bus stop, unless there is a 0th bus stop:
0th stop (if someone requests): right after the tollgate: a few people might get off there.
1st stop: Do-Ryong-Dong: a few people get off here. Sometimes the driver simply asks to the passengers and if no one requests, the bus might continue.
2nd stop: Government Complex Building (Jeng–Boo–Cheng–Sah): in a busy downtown. Most people get off here.
3rd stop (final): Daejeon Eastern Express Bus Terminal

To take taxi to KAIST: If needed, show the following taxi card. It says “Please go to KAIST, Natural Sciences building. Take a right at the main gate, and you’ll see on your left the building E6-1.

카이스트 자연과학동으로 가 주세요.
정문에서 우회전해서 직진 후  왼쪽에 있는 E6-1 빌딩입니다.

4. Alternative method: Train

You can first go to Seoul station by train (every 30 minutes) and then go to Daejeon station by KTX train. You can buy a combined train ticket to Daejeon at Incheon airport. This method will be more expensive and yet save you at most half an hour. On Friday evening, KTX to Daejeon is usually full.

Or, there is a bus to Gwangmyeong Station and then take the KTX train to Daejeon.
