Hotels adding charges to guest bills after they checkout

Interesting story about hotels that "revise your bill" after you checkout:

If you think your hotel’s done with you when you check out, think again. It might just be getting started.

Charges can be quietly added to your hotel bill after you’ve left. And increasingly, they are.

...That’s what happened to Charles Garnar when he stayed at the Renaissance Fort Lauderdale Hotel recently. “When we checked out, we were told there were no charges so we had a zero balance,” he remembers. But when he returned home after a cruise vacation, he found an unwelcome surprise on his credit card statement: a $57 charge. “It took two days to get through to the accounts-payable department,” he says. “They said we used the minibar.”
