It's easy to pair a visit to Disneyland with a short cruise. Disney doesn't offer official package deals, but you can create your own.
Disneyland is in Anaheim California, only about 30 miles from the port of Los Angeles. Disneyland Park is the original theme park. It is divided into 8 lands -- Main Street, Tomorrowland, Fantasyland, Mickey's Toontown, Frontierland, Critter Country, New Orleans Square and Adventureland. A few of the famous attractions are Space Mountain, Splash Mountain, Pirates of the Caribbean, Matterhorn Bobsleds, It's a Small World, Indiana Jones Adventure, and the Monorail.
The other theme park there is Disney California Adventure Park. It is newer and has 7 lands including Buena Vista Street, Cars Land, Grizzly Peak, Paradise Pier, Pacific Wharf, A Bugs Land, and Hollywood Land. The attractions are based on Disney and Pixar stories.
