The closest available parking is Valet parking at the Sheraton hotel entrance. The Valet parking is $15 a day, and can be billed directly to your room if you are staying at the hotel.

Alternatively, the Century Center provides event parking for $5 or 24 hour parking for $7. It is located attached to the Sheraton Hotel and Convention center, with the entrance on the South Side.

Metered street parking is also available throughout downtown. Street parking is free after 6pm and on Sundays.

Free parking is also available in lower bricktown, with a free trolly running between Bricktown and Downtown OKC (a stop is directly in front of the Sheraton). Trolly information is available here.
