I just had a recent stay where I had to prepay 1 night deposit. The credit for my deposit appeared on my folio. When I asked to have the prepayment refunded to my credit card so I could pay the entire bill with gift cards, the agent at the desk had no issue updating the folio, which removed the credit for the prepayment, but said that accounting would separately issue the refund to my card.
