Traveling with a group, the accommodation said that one person should make up the price difference of a single room, and it is not possible to open a single room. Really?

For example, a room in 200 yuan, then this room has two beds, and the average cost of one person is 100 yuan; If you want to live in a room by yourself, you have to pay the room rate, so you have to make up the difference.

At present, most hotels charge by room, and rarely by bed.
