Parking tonite

First time I’ve ever driven to a game at the Princapality Stadium and need a pretty quick exit,any recommendations for parking?Maybe our Stadium And walk up but run back.Is it free parking in the CCS tonite?
Need to be in work 10:30

Don't make the mistake of parking in Grangetown where there is permit parking in many places.Nights like these the local authority make a fortune giving tickets to people taking a chance.
