Is it legal for the hotel to stipulate that adult children cannot share the same room with their parents?

"Adult children can't live in a standard room with their parents" infringes on the legitimate rights and interests of consumers.

Obviously, this is illegal. First of all, from a legal point of view, there is no law prohibiting adult children from living with their parents. For private rights, the law can be done without prohibition. The Law on the Protection of Consumer Rights and Interests stipulates that consumers have the right to choose their own goods or services, choose their own types of goods or services, and decide whether to buy or not to buy any kind of goods or accept or not to accept any kind of services. Without any legal basis, hotels do not allow adult children to live in a standard room with their parents, which obviously violates the legitimate rights and interests of consumers and is illegal.

It is also illegal for hotels to refuse on the grounds of "general industry regulations".

As a service place, hotels should provide better services for customers and meet the actual needs of consumers. It is obviously illegal for hotels to refuse based on the general regulations of the industry. In the absence of legal provisions, it will not be legalized just because there are general provisions in the industry. After all, the reporter called the Beijing 12345 citizen hotline to inquire about this matter, and the staff also answered the specific number of hotel accommodations, and there was no uniform regulation. The staff of China Tourist Hotel Association said that the association has no regulations. It is obviously illegal to rely only on the common practices of the hotel industry without legal provisions and industry norms.

In this case, how can consumers protect their legitimate rights and interests? As consumers, when their legitimate rights and interests are infringed, consumers can report and complain to local consumer associations; In addition, because consumers paid the fees on the online platform, the two parties formed a contractual relationship in law. The hotel's refusal to stay in the hotel is obviously a violation of the law and the contract (even if the contract stipulates that adult children should not stay with their parents at the same time, I think this clause is invalid). As consumers, they have the right to take up legal weapons and bring a civil lawsuit to the people's court, demanding that the hotel perform the contract and protect their right to stay.
