was there evidence that the hotel made a mistake?
Having one receipt showing total due $388, amount credited from her card $388 - balance $0 .. Then another receipt showing total due $388, amount credited from Caz's card number $300, balance $88..

was there evidence that the card was not used in an attempt to pay for someone other than the card holders room?

Her receipt shows it wasn't used to pay for her room..
