In general, you will not be charged a cleaning fee if things are a little messy. Even if you don't intend to do so, you may have seriously defaced or damaged the hotel's items. First, ask the hotel for a billing statement and check the details of what you are paying for. The bill may include the actual cost of repairing or replacing the item, as well as the loss of accommodation for the period when the room is out of service. If you are not satisfied with the charge or the amount, ask the hotel to explain the reason for the charge and how it was calculated. If you have overseas travel insurance, you may be covered by that insurance. Also, check what kind of insurance plan is included in your credit card.
