Is Ctrip's deferred payment reliable? Will it be said that there is no room at that time?

Ctrip's deferred payment is reliable. The service reservation page will add the "delayed payment" option. This means that consumers do not need to pay immediately when booking such hotels, and Ctrip will automatically collect money before the stipulated payment date. If you cancel the order before the payment date, you can save the tedious refund process.
