To enter the parking garage of the Hilton, you need to turn south from Wisconsin avenue to 5th Street. 5th Street is a one way street by the hotel, only going south. Just past the hotel, on the same side of the street as the hotel on 5th street, there is a sign pointing into the parking garage that says "hotel parking." It is $38/night. To enter/exit hotel parking lot, you will insert your room key.
