I did not park at the mall. I parked in a parking lot near the Alamo.Some parking areas charge a set fee regardless of how long you want to stay. Fee is $10-15. Others give options like $13 per 4 hrs, $21 per 6hrs, $25 per 8hrs. Some lots only take credit/debit cards. The on-street.parking meters are different but I haven't been lucky enough to find one.
I second S. Lopez. We did find one garage where it was $10 for the whole day. Cheapest we found in the city.
