Why are the rooms in the hotel connected?

The room described by the subject is called "connecting room". Most townhouses were originally designed to meet the needs of guests, for example, a family living together can be sold as a suite. Usually it can also be split into two independent rooms for sale. Kill two birds with one stone. There are also some hotel rooms that were designed too big in the early stage or originally designed as suites, and later converted into two adjoining rooms.
