Parking is horrible, but doable. The more you pay the easier it is. There are lots of small lots that will take your money. If you get there early it should not be too difficult to park reasonably close to the stadium.

My recommendation is the purchase in advance in one of the few structures that allow it. If you go to USC’s parking website I think for $30 you can buy a spot in the Downey Way structure, that is on campus and a relatively close walk to the stadium.
