Hotel parking is rather expensive. I recommend that you take the Metro Red or Purple Line to Metro Center and walk across the street to the hotel and take the elevator up to the 73rd floor
There's a public parking lot, right across the 7th and Fig shopping center. Adjacent to Bank of America. Parking lot is usually $8-$10. Lot closes at 2am. Then walk a few steps the Intercontinental hotel.
Metro is the best way to go.
