The check-out agreement of the hotel contract said that the rent was withdrawn two months ago, but it was not fulfilled. Is it a breach of contract?

Count. According to the terms of the contract, the check-out agreement stipulates that the tenant should inform the landlord or hotel two months in advance, otherwise it will be regarded as a breach of contract. This means that tenants have to pay extra fees or bear other consequences. If the tenant fails to notify to check out on time, but the landlord or hotel has successfully sublet the room (or found a new tenant), then the tenant does not need to pay any liquidated damages or other fees.
