Small legal point. Contracts are not allowed to impose fines. They can cite liquidated damages (what most people see as a fine) but they have to be rationally related to the damage done by the activity described. They cannot be arbitrary or elevated simply to deter unwanted behavior. Yes, this is and issue when it comes to "parking tickets" on private property.
500$ fee to accommodate a cleaning crew = 0k.
5,000$ fine for pain and suffering caused by naked people in someone's home = not enforceable.
After all, isn't that essentially how overdraft fees work? "Oh, you want to withdraw $2 when your balance is $1? That constitutes a request for a loan, for which we charge a $35 fee."
It might have a liquidated damages clause if the use of and stipulated amount of liquidated damages was such as to be found reasonable for the type of breach it covers; otherwise, a "fine" in a contract is generally an unenforceable penalty clause.
But the company has historically never had qualms about screwing their customers over, so I wouldn't hold my breath.
