Is it illegal for couples to quarrel in a hotel without calling the police and asking the front desk for personal information?

It is inevitable to book a hotel when traveling. Generally, if you stay in a hotel, you need to show your ID card, not only to show your identity, but also because the hotel needs to record the information of customers. Some people may think that two people living in a room only need to register one person's ID card, but this is not the case. Especially for people who are not husband and wife, it is illegal to register only one person in the same room.

Avoid multiple rooms in one room. There are usually two or three people in the hotel's big bed room and standard room. But some people have no money, so they want to open a room for many people to share. In hotels, this is illegal and usually not allowed, so someone uses an ID card to open a room and then secretly takes someone in. So what are the consequences of this registration method?

This registration method is not desirable. If the police check in and find many unregistered strangers living in the same room, the registrant will bear the corresponding legal responsibility. What's more, it will be suspected of gathering people to commit illegal acts and taking them to the police station for the record.
