Is it illegal for a hotel to refuse to stay without reason?

It is generally illegal for a hotel not to check out. According to the law, consumers need to check out due to force majeure. If the hotel disagrees, they can bring a lawsuit to the people's court. However, if consumers check out after booking a hotel without deciding or agreeing to cancel it, they need to bear the corresponding liability for breach of contract.
