I know they are always re-inventing various parks, but right now CA Adventure is going through some big changes.
I would wait until next year when they are all done. We live in CA and are considering taking a year off of having season passes to wait until it’s all done.
As far as the question of which one is better the answer is “neither”. They are both unique in their own way and should both be experienced by people who consider themselves Disney fanatics.
You need half the time here in CA than you do in Florida because, hey, they have twice as many parks in Florida…duh…lol
There are many things to do close to DL. Knotts Berry Farm is an amusement park that is just a 10 minute drive from the DL hotel and is a great day trip.
There is also Hollywood, Malibu and many other things to see in the area.
