You can't miss it!
Head north on 101 (I think). come off at Oxnard. Head for the Marriott Hotel. Enormous car park. No problems at all. great venue. Loads of viewing spots.
hopefully will see you there - but has to be ok'd by my other half yet!! Mapsonus also give you a good route.
If I can find my wasy there from over here, then anyone can get there!
Ps - if lost, head for Oxnard Airport- v close to it.
