What is the meaning of "children occupying the bed price" in travel agency charges?

The reason for this is that hotels generally pay accommodation fees according to bunks, and the prescribed standards are all according to the standards of adults. If you are with children, some adults don't want children to sleep alone, but want to live with themselves. They can choose 1 adults 1 children for a double room, and two adults 1 children for a triple room, at the standard charge. You can also choose two adults with 1 child to open a double room and then add a cot. At this time, the child is charged the bed price, which is slightly cheaper than the method of 1.
