We live in Southern California, grew up going there. Wife wanted to go for her birthday a couple years back, I'd have to say it was fun, more fun in California Adventure where they sell alcohol and the rides are better :) But at Disneyland all the classic rides are still fun to do once. Pirates, Space Mountain, Haunted Mansion etc. Brings back good memories

That said, it's like Vegas for us. One day every 5 years (or more) is good enough.
