How can I return the hotel if I can't cancel it?

Contact the hotel first, tell the reason and ask if it is possible to cancel. If the hotel agrees, you need to contact customer service again, indicating that the hotel agrees to cancel and hopes to cancel the order. Customer service will help you negotiate. But if you can't cancel it in the end, there's nothing you can do. Maybe through a broker or something.

There are currently the following hotel orders:

Guaranteed order: pay the full room rate to the reservation platform in advance as a guarantee, and pay the room rate and deposit to the hotel upon arrival. After departure, the reservation platform will refund the deposit. Orders cannot be cancelled or changed. If you do not arrive at the hotel, the deposit will not be refunded. The hotel will reserve the room unconditionally until the check-out time.

Prepaid order: pay the full room rate to the reservation platform in advance, and only pay the deposit to the hotel after arrival. The order cannot be cancelled or changed, and the room rate will not be refunded before check-out. The hotel will reserve the room unconditionally.

Pay-as-you-go unsecured order: you can book a hotel without paying any fees, and then pay the room rate and deposit when you arrive at the store. Because this kind of order is not binding on consumers, there is a retention time limit, which is usually 8 pm or 12 pm on the day of check-in. This time should be set by the hotel itself. Very few now, because hotels are not guaranteed. If this model is still used now, it shows that the business situation of this store is not good.
