Yes! Most hotel room reservations are refundable provided that you cancel before the hotel's cancellation deadline, which is often 24 or 48 hours before check in. If you have a non-refundable reservation, it might still be possible to cancel it and be given a refund within a 24-hour period of your booking. Add dates, click "Search", then use the "fully refundable" filter to get the best options available near Shengjin Lake.
