What will happen if you book a hotel and don't stay?

There are no consequences. If you pay the money, you may not get a refund. Nothing else. If you don't check in at the scheduled time, people will cancel it for you.

Online booking is divided into online booking with full deposit, online booking without deposit, direct payment at the front desk after arrival and online prepayment with full deposit. It should be noted here that online reservations are collected by agents, so you need to contact the agent first instead of the hotel. Generally, the first and third kinds are not changed or cancelled because they are basically on sale. Under normal circumstances, the hotel will keep the guaranteed reservation all night, and even if it arrives in the early morning for irresistible reasons, the hotel will always keep the room for you. In case of weather, flight cancellation, etc. , you need to submit relevant certificates (the airline will issue them). Or contact the network provider and hotel at least 2 days in advance to deal with it in time. If you don't check in for your own reasons, hotels and internet providers won't refund you.
