I'm going to disagree with some of the other responses. I thought the Animation Studio was interesting, but I wouldn't go out of my way to see the things there. I absolutely LOVED Turtle Talk with Crush, though--don't miss that one!
Soarin' Over California is amazing, not to be missed.
The tortilla factory was a yawner, although the fresh one(s) they give you at the end are pretty tasty. I didn't go on the bakery tour, but I did eat there. Had tortilla soup in a sourdough bread bowl, and it was delicious. I also bought a very cute Mickey-shaped sourdough loaf.
My kids loved the Block Party Bash. For us, there was no "best" place to be; we just stood in the plaza and enjoyed it like everyone else. Watch at the end for them to shoot out a bunch of little foam balls into the crowds. They're a little smaller than raquetballs (and thankfully not as hard!), and have "Block Party Bash" printed on them. Fun little souvenir.
We liked Aladdin more than we expected to. LOVED Monsters, Inc. Tower of Terror was terr-ific. The midway rides are typical. We hated the ferris wheel, which I called the Wheel of Terror. We were in one of the "cages" that move on a track, and there's nothing to hold onto inside the cage. I kept apologizing to the guy in front of me because I was sure I was going to end up in his lap a few times. It was way too long (slow-loading) and the view wasn't worth it (in my opinion).
A Bug's Land is really for the younger kids, with the exception of "It's Tough to be a Bug." That show is good for older kids--it was sorta scary for ours--and I thought it was great. Heimlich's Chew-Chew Train was very cute, but unless you're a huge fan of "A Bug's Life," it's probably not worth going. Tuck & Roll's Drive 'Em Buggies are cute to look at, but not all that fun to drive. The Fun Fair is best for little ones. Besides "It's Tough to be a Bug," my favorite part of this land is all the little details--the lights, the buildings, etc. are really well done and makes you feel sorta like you're in the movie.
