Reserve a full day to see the newer park -- two days if you visit Disneyland too. To make the most of your time, pick up a free FastPass at machines just inside the park entrance. With the pass, you'll skip those long, snaking lines for the park's top rides -- the computer will assign a boarding time for each ride requested, so you can eat or visit other attractions, without the mad dash.
In typical Disney fashion, you'll take a monorail, tram, or bus from the parking lot to the main gate. Once there, look for the 12-foot-high letters spelling out California and a stylized replica of the Golden Gate Bridge. You can't miss them.
