you can simply make s new booking for another period of stay.
As long as the booking shares common booking name, and is made under the same room type, you will be in the same rooa/bed for the entire stay.
제가 따로 make a booking 할때 똑같은 이름 똑같은 share room으로 하면 전체 숙박을 똑같은 곳에서 진행할수있다는말이지요?
능력자님들, 미리 감사드립니다. 꾸벅!
