Disneyland is the park that started the theme-park industry as we know it today, and it set the standard for the parks that followed. The basic lands of Walt Disney’s original “Magic Kingdom"-- Main Street, Tomorrowland, Fantasyland, Frontierland, and Adventureland--are probably the most copied of all theme-park concepts, and this is the park with most of the original versions of classic Disney attractions.
The park is smaller in scale than its cousins in Florida, France, and Japan, and weekends usually mean huge crowds, no matter what the season. Your best bet is to get to the park before opening and hit as many attractions as you can before the park becomes crowded. If your group has any small children, you might want to get the lower-capacity Fantasyland attractions, such as Dumbo or Mr. Toad's Wild Ride, out of the way first. And remember this rule of thumb: Before you queue up for one ride, have a Fast Pass in hand for another.
