is better. It's not. it is worth doing if you are going more than 1 day, but if you are going for only one day, Disneyland is what you want to do. I have a 3, 6, 8, 10, & 12 year old. Disneyland is their favorite. Radiator Spring Racers in California Adventure is pretty sweet though. Cal is slightly more geared to teenagers.
