Only Have One Day at Disneyland? Yes, It Is Possible to Do Both Parks

Take advantage of the time during the day that people are lining the streets waiting to watch the parades and go on rides instead. It's the nighttime shows that are really worth staking a place to sit or stand. Try to get in the fireworks at Disneyland and World of Color at California Adventure. They scatter the show times so you should be able to get in both!
