The transit accommodation of Korean Air.

Korean flight KE072 flies from Vancouver to Seoul 14 10, takes off 1740 and arrives in Seoul. When the plane is about to arrive in Seoul, the crew on KE072 will inform all passengers of the flight, and assist the passengers who transfer to the airport to find a convenient passage for the ground crew to take the transfer according to the established procedures, which will be arranged by the airport. Under the escort of airport security guards and airline professionals, take the designated shuttle bus to the hotel designated by Korean Air for one night, return to Seoul Airport at about 4 or 5 o'clock the next day to check in, take KE845 flight 08 10 to Qingdao, and take off at 0840 to arrive in China.

If your passport has an entry visa to Korea, that's no problem.

If there is no Korean entry visa, because according to what I said above, you may not be able to leave the hotel by yourself, right?
