Can unmarried men and women stay in hotels?

Yes, but you need to meet these three requirements.

First point: Both parties must be 18 years old.

The premise is that both parties must be adults. If they are not adults, they won't know whether they have been cheated or forced to go to the hotel with others. And minors are not allowed to stay in hotels with strangers. If the hotel knew that they were minors, it would definitely not check you in.

Of course, if you go with your parents, that's fine. But you must also provide proof that it is your child, otherwise in order to protect minors, the hotel will not stay.

The second point: both sides should be sober or after consultation.

This is also easy to understand. If one of them is unconscious, the other person will take your ID card and help you to check in at the hotel. Who knows whether you are willing or not? Even if you say yes, who knows if you are talking nonsense after drinking? Besides, when the other person is unconscious, who knows if he is drunk, or tripped over by others and ate something bad?

So just to be on the safe side, Miss Front Desk won't go through the formalities for you.

Of course, it's almost the same as without prior discussion between the two sides. If they hadn't discussed it in advance, they would have checked in. You want two rooms, others want one, and they are arguing in the hotel lobby. How many rooms should the receptionist open? Therefore, in order not to offend people, my little sister will not open it for you, but will invite you aside or go out to quarrel. After discussion, the two agreed to open a room for you.

The third point: provide identification.

This is the best to understand. Which hotel doesn't provide ID cards now? If you forget to bring it, you can use it with an electronic ID. You can also enter relevant information at the front desk and then recognize the face, or you can handle it.

But both parties brought their ID cards, so they asked the front desk to enter one person's information and booked a room for two people. This is unacceptable, because the hotel has regulations that two people should check in. If only one person's information is registered, it will not be processed. Because the hotel doesn't know whether the person who doesn't give identity information is an adult, a "bad guy" and so on. So for the sake of safety, you will be asked to fill in your identity information before going through the formalities for you.
