Is it illegal for the hotel not to cancel the order?

Legal analysis: it is illegal. If a tourist cancels a hotel reservation unilaterally, it does constitute a breach of contract and needs to bear the liability for breach of contract. However, the liability for breach of contract is stipulated by law. Both parties need to agree on reasonable liability for breach of contract according to the consequences of one party's breach of contract and the losses caused to the other party, and cannot cancel the subscription. Legal basis: Article 52 of the Law of People's Republic of China (PRC) on the Protection of Consumer Rights and Interests, if a business operator provides goods or services, causing damage to consumers' property, it shall bear civil liabilities such as repairing, redoing, replacing, returning goods, replenishing the quantity of goods, returning the payment for goods and services or compensating for losses in accordance with the law or the agreement of the parties. If one party fails to perform the contractual obligations or fails to meet the contractual obligations, it shall be liable for breach of contract, such as continuing to perform, taking remedial measures or compensating for losses.

If one of the parties expressly expresses or shows by his own behavior that he will not perform the contractual obligations, the other party may require him to bear the liability for breach of contract before the expiration of the performance period.
