Is it reasonable that the hotel does not allow adult children and parents to stay?

I think it is unreasonable for hotels not to allow adult children to share a standard room with their parents for the following reasons:

Hotels do not allow adult children and parents to live in standard rooms, which is a restriction on consumers' freedom of choice. When booking a hotel, consumers should have the right to choose the appropriate room type and number of people according to their own needs, budgets and preferences. If the hotel refuses a family of three to stay in the standard room due to industry regulations or other reasons, it is unfair to consumers and improper intervention in the market.

The hotel does not allow adult children to live in a standard room with their parents, which is a misunderstanding and interference to family relations. Family is the basic cell of society, and there is affection, trust and respect among family members. Adult children living in a standard room with their parents does not mean that they have any improper relationship or behavior, but a normal family interaction and companionship. If the hotel refuses a family of three to stay in the standard room for moral or other reasons, it is a misunderstanding and interference to the family relationship, and it is also a misleading and destructive to the social atmosphere.

Hotels do not allow adult children to live in a standard room with their parents, which is detrimental to the interests of consumers. When booking a hotel, consumers often choose the most suitable price and service according to their actual situation. If the hotel forces a family of three to stay in a family room or other more expensive rooms, it will harm the interests of consumers and disrupt market competition.

To sum up, it is unreasonable for hotels not to let adult children and parents live in a standard room, and it should be cancelled or modified.
