It always helps to be prepared when navigating downtown.
Parking downtown typically starts at $8 or higher. Be sure to bring cash so that you can park.
The most common places to park are under the Convention Center (but get there early!) and at the Santa Fe Plaza Parking Garage.
You may also wish to park in Bricktown and take a short walk (usually 3–4 blocks).
There may be some free parking in lower Bricktown (near Toby Keith and Bass Pro).

It's always a good idea to do a search for construction downtown to see if there are any areas you should avoid.
