Booked a hotel online, pre-authorized, and finally didn't check in. Will the money be refunded?

Do you mean that after you booked online, you went to the hotel and paid a deposit?

Generally speaking, you didn't check in, just paid in advance. /kloc-After 0/month, the money will automatically return to your card.

But you should make sure that you are paying the deposit instead of the deposit (advance payment). Many hotels have strict distinctions. The deposit can be refunded, but the deposit (advance payment) cannot be refunded.

Personally, I suggest you contact the hotel front desk in time to ask whether this pre-authorization is returned. If yes, ask the other party to cancel the pre-authorization immediately.
