The hotel has been booked, but can I return it if I don't check in?

You can negotiate with the hotel for refund or change of time, negotiate with the hotel for sale, and negotiate with the US Mission for complaints. The first and most direct way is to negotiate with the hotel staff, be honest with each other, negotiate a refund or change the check-in time. The second method is to negotiate with the hotel and let the hotel sell the room on its behalf to minimize the loss. The third method is to call the Meituan platform, which will coordinate the refund and inform the Meituan platform that it cannot stay because of non-personal accidents. Fourth, you can complain directly to the Consumer Protection Association.
