We LOVE California Adventure, and spend almost as much time in that park as in
Disneyland.
We love Tower of Terror, Soarin, Grizzly River Run, and lots of the other rides.
The Bugs area is so cute, take the time to walk through it and really look around, it gives you the perspective of being a bug (everything around you is huge, like a cracker jack box, bottle top etc...)
Its Tough to be a Bug show is great.
The Block Party Bash is awesome. If it is still on, go and see it! It is great! All the energy and fun!
The Electrical Parade is so neat. Very Disney and very aaaahhhhh.
We enjoyed the Boardwalk area, just seems fun and beachy.
Take the time to go in the Animation building. It is neat to see how the cartoons are made. Also the little presentations in there are cool. Mushus show is neat, and Turtle Talk with Crush is worth seeing a few times.
Our favorite though..... The Aladdin Show.
Broadway quality, for free!! It is amazing, a must see!
We love that if Disneyland is too crowded, we can hop over to CA. It isn't as busy, and has lots to do to keep you amused. We love it! I could go on and on!
