Tips for California Adventure in the Disneyland Resort:
Sometimes they allow people in about 30 minutes before scheduled opening to line up for the Radiator Springs Racers Fastpass, so make sure you arrive early.
If you want to arrive for park opening, do not use gates at the Grand Californian as it can be much slower than going through the main gate.
If you arrive at the gates early, they will scan your ticket before they open the park which will allow you to enter very quickly.
Pick a line with a energetic, spry looking cast member for faster entrance.
