Can adult children share a room with their younger brothers and sisters under the age of 18?

It is reasonable for hotels to allow adult children and parents to live in a standard room, but the specific situation depends on hotel policies and local laws and regulations.

Generally speaking, if it is a star-rated hotel, it is best to abide by relevant local laws and regulations and hotel policies. Some hotels stipulate that only two people can stay in a standard room. If extra beds or three people are needed, there may be an extra charge. However, some hotels may provide free extra beds or allow three people to live in one room. In this case, it is generally necessary to contact the hotel in advance to confirm.

In addition, some countries or regions may have special regulations, for example, the public security department requires hotels to register passenger identity information, and family members living together must be husband and wife or immediate family members. In this case, it may be necessary to provide relevant supporting materials before going through the check-in formalities.

Generally speaking, if the situation permits, it is best to choose a hotel with more relaxed accommodation conditions, or contact the hotel in advance to learn more about relevant policies and requirements, so as not to bring unnecessary trouble to travel.
