They do charge $10.00 per night. I have not heard of them waiving the fees.
HOWEVER, if you have your own transportation available (such as rental car or using limo rather than bus from the airport) you can stop by a large drugstore or a supermarket and buy a styrofoam ice chest for about $4.00 and keep it filled with ice from the ice machines and then abandon it at the end of the trip. That is what I do; it is much cheaper than renting a refrigerator.
