A fee for parking each day was added to the stay. This was not mentioned when booking the room through Expedia. In fact, Expedia still states "Hotel with free parking." and "Parking Included."
The Hampton Inn and Suites does have the Parking Fee noted on their website, although the attendant at the hotel stated they had only been charging the fee for a few weeks, which means that they started the parking fee after I booked and paid for the hotel stay.
