Hollywood, where all the worlds weirdos come.
spend the day at Universal Studios...it's awesome for all ages.
Six Flags Magic Mountain (45min drive up freeway) is the place to go if you love roller coasters.
Disneyland was awesome (get the early morning pass, allows 1hr earlier access before the gates open to public so you can knock out more rides before the crowds)
Sea World San Diego is 1.5hr drive South from Disneyland, get the $28 breaky show (can book on line) we we're within a meter of the killer whales and is a smorgasbord breaky that's nice food.
(spend the extra for gold/VIP pass at any theme parks to avoid lineup, only way to see all)
Also if you want Happy Days style cafe that serves the best thick shakes and a burrito I drove 3hrs back to gave a second time, Snug Harbor the best burrito I've ever eaten and is rated one of the best in US
