The flight has been cancelled. Can I cancel my hotel room reservation and get a refund?

Under normal circumstances, you only need to notify the room reservation more than 24 hours in advance, otherwise there will be no refund. Some reservations require you to inform them three days in advance. If you cancel near the check-in time, people there will mistakenly think that you will definitely arrive, leave the room for you and refuse others to book that room. In fact, you didn't arrive, and this is not the loss of the hotel. It is reasonable not to return.
