Why Does a Korean Hotel Take a Deposit After You Paid?

Paying in advance normally settles the booked room rate. A check-in deposit usually secures later incidentals—minibar, dining, laundry, damage or an agreed late checkout—so it is not automatically a second room payment. Yet the word “deposit” is used loosely. Before approving anything, identify the amount, whether it is a pending authorization or completed charge, and which card is being used. This is payment-process guidance, not a promise about a particular hotel or issuer.

One booking can create three card entries

A posted room payment is the room charge already collected. A pending authorization reserves spending power and may later disappear or be reversed if unused. A posted incidental charge is a finalized amount that remains unless adjusted or refunded. A third-party platform may have settled the room through its own method while the hotel still needs the guest's physical card for possible incidentals. The booking receipt proves prepayment; it does not give the hotel a payment source for a bill that has not yet been created.

Ask before the card touches the terminal

There is no single Korean hotel-deposit amount. Marriott's official explanation gives a chain example in which an authorization can cover room, taxes and incidentals, while Hotel Riviera Cheongdam publishes its own preauthorization language. Neither creates a national rate or policy. Ask: “What is the exact amount in won? Is this a hold or a charge? Is it per night or per stay? When will the hotel release it?” Cash, debit, prepaid and app-based cards are not universal substitutes; the exact property must confirm acceptance.

Debit makes the hold a cash-flow problem

On a credit card, a hold generally reduces available credit. On a debit card, it can reduce the cash balance available for meals, transport and the next hotel even when no final charge has posted. Traveler discussions show mixed property practice, which is useful as a warning but not policy. If debit is the only option, ask the hotel before arrival whether that exact card type supports hospitality authorization and leave enough untouched money that the trip still works while funds are unavailable. A card that buys groceries is not guaranteed to accept a hotel preauthorization.

Release is two separate handoffs

At checkout the hotel closes the folio and releases, reverses or converts the authorization. The network and issuing bank then control when available credit or cash is restored. Marriott's published timeline is a large-chain example, not a guarantee from every Korean property, bank or international card. Weekends, cross-border processing and issuer rules can extend the visible pending period. A reversed authorization may simply vanish rather than appear as a positive refund.

Keep a small evidence file

Collect the final folio and ask the desk to confirm the authorization was released. Keep the hotel name, checkout date, amount, currency, release confirmation and only the last four card digits—never send a full card number in ordinary email. If it remains past the window quoted by the hotel, ask whether it was reversed, voided or captured and request an authorization reference for the issuer. If both the prepaid room payment and a second completed, not pending, room charge appear, compare the folio and report the possible duplicate promptly.

The calmest check-in is one where the amount and card-entry type are clear before approval. Prepayment covers the stay you booked; the hold protects a possible later folio. They can coexist, but neither the hotel nor a forum can guarantee the issuer's release display date.
