You can PARK (no overnights though) in Disneyland, and at Universal. Most attractions often include information about parking, California is just so busy ya know. Universal lists RV parking at $17.00 . Also you can try this. If you decide to try for one of the beach lots (Dockweiler or Bolsa Chica) you would want to try to snag your reservation as soon as possible. Also this option: Anaheim has some commercial RV parks and it isn't that hard to get from Anaheim to LA by Metro Link. Hope this helps good luck and enjoy your vacation.

Multiple public parking all around
