You checked in, handed over a card, and your banking app now shows several hundred less available than you had this morning. Nothing has been taken. What the hotel did is called a pre-authorisation, and it is one of the most alarming and least explained things in travel.

What a pre-authorisation is

The hotel asks your card issuer to reserve an amount against your available credit or balance. The issuer agrees and ring-fences it. No money moves. Your available balance falls; your actual balance does not.

The hotel does this because it will not know the final bill until you leave — minibar, restaurant, spa, late check-out, damage. Rather than chase you afterwards, it reserves headroom in advance.

What it is for

  • Incidental charges during the stay
  • Damage or missing items
  • On a pay-at-property booking, the room itself

Typical amounts run from a modest fixed sum per night to the full value of the stay plus a margin, depending on the property. Resorts and higher-end hotels hold more. It should be disclosed before arrival, and if it was not, ask at check-in what the amount will be before you hand the card over.

When you get it back

This is where the frustration lives, because there are two separate events and only one of them is visible.

At check-out the hotel releases the hold, usually the same day. That instruction then has to reach your issuer and be processed. Depending on your bank and card type, the reserved amount typically disappears from your available balance within a few working days, and occasionally takes up to around 30 days on some debit cards.

The hotel genuinely cannot speed this up. Once released, it is between your bank and the card network. What the hotel can give you is written confirmation that the release was issued, which is the thing your bank will ask for.

Debit cards make this worse, and it is worth avoiding

On a credit card, a hold consumes credit you were not using. On a debit card, it consumes your own money, and you cannot spend it while it is held.

A €400 hold on a debit card on the first day of a trip is €400 you do not have for the rest of the trip, and it will still be unavailable for days after you get home. Some hotels will not accept debit cards for the deposit at all, and some refuse cash deposits.

If you have a credit card, use it for check-in. You can pay the final bill however you like.

Cash deposits

Some properties, particularly smaller independents and in cash-heavy markets, ask for a cash deposit instead. This is legitimate but carries a practical risk: getting cash back at 6am on departure day, when the person who took it is not on shift and the safe is locked, is a genuinely common problem.

If you leave a cash deposit, get a signed and dated receipt, and confirm at the time exactly when and how it will be returned.

The two things that actually go wrong

Double holds. A hold placed at booking and another at check-in, both live at once. This is usually a systems artefact rather than an error of intent. Point it out at the desk; they can normally release one immediately.

A hold that never releases. Rare, and almost always because the release instruction was never sent. Contact the hotel first and ask them to confirm the release in writing. If they confirm it and your bank still shows the hold after roughly a week, take that written confirmation to your bank.

Before you arrive, ask two questions

Email the hotel and ask: what is the deposit amount, and do you accept debit cards for it?

Two sentences, sent a week early, prevents both of the situations that ruin the first hour of a trip: an unexpected four-figure hold, and a card the hotel will not accept.

Villas and vacation rentals

Larger deposits are normal here — the exposure is a whole property rather than one room. More importantly, the terms differ: some rentals take a genuine refundable deposit as a real charge that is refunded after inspection, which is different from a hold and takes longer to come back.

Read whether it is a hold or a charge. They behave very differently, and only one of them is invisible to your actual balance.
