Is it illegal for the hotel to refuse to add quilts?

According to relevant information, it is illegal to add quilts to hotels. When a consumer stays in a hotel, both parties establish a service contract relationship. The service content, including the price, beds provided, service implementation and other information, depends on the contract. Hotels belong to the service industry, and adding quilts can't be refused according to industry practice. Refusing to load is illegal and infringes on the legitimate rights and interests of consumers.
