Hotels place a "hold" or "block" on your credit card at check-in as a form of financial insurance for incidentals and damages. This hold typically covers the total cost of the room and taxes, plus a daily "security deposit" (ranging from $20 to $200 per night) for potential charges like room service, minibar use, or property damage. By placing this hold, the hotel ensures that you have enough available credit to pay your final bill before you check out. In 2026, these holds are more transparent, but they still reduce your "available credit" limit for several days after your stay. If you use a debit card, the hotel actually "pulls" the cash from your bank account temporarily, which is why most travel experts recommend using a credit card to avoid a temporary loss of liquidity in your checking account during your vacation.
