Is it reasonable to set an irrevocable clause in the hotel?

Legal analysis: it is unreasonable for hotels to set up irrevocable clauses. The hotel's terms such as "no refund once booked" or "no cancellation" are all suspected of constituting the overlord clause. 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, and both parties need to agree on a 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.

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.
