I usually park at the Crown Plaza structure,good deall for AAA members.
If you have an early flight The Renaissance LAX has a great park and fly package.
The one time i tried to save some $$$ I parkes at on of the many discount lots on La Cienega-Fox-never again,all you save is a buck a day,the lot is very open and shuttle service is spotty.All of that to save $1 a day I don't think so!
