Do you offer any passes or discounts for residents of California or otherwise? Thank you

Yes, you can get the southern California pass.

Yes there are discounts but with black out dates

Yes, they do. You'll need to prove that you are a resident. You can get discounts on multi-day tickets and there is a special annual pass for California residents too. But there are a lot of blackout days (days you can't go to the parks with that specific pass) check before you buy that one.
