The hotel refunded the pending transaction, so they are the party that suffered the financial loss. If they hadn't done that, then the credit card company would have done a charge-back on the disputed transaction and made me whole, and I wouldn't have suffered a loss in that case either. The first question the police forms for reporting fraud or cybercrime are "how much have you lost" - they don't care if it's 'nothing'.
It's the hotel that has to clean the room, has lost consumables, and has lost revenue from it not being available to be booked...
