I charged $200 on my prepaid card at a hotel, but my account shows a charge of $230. Why?
This may have happened because the hotel put a temporary hold on your card. Many hotels may require a deposit in addition to the room charges. If that’s the case, the hold on the deposit will be removed when the transaction is processed, which may take a few days or longer.
You should call the hotel ahead of time to inquire about their deposit policy and the length of a temporary hold if you pay by a prepaid debit card.
