Candidate passages:
Disneyland Park, originally Disneyland, is the first of two theme parks built at the Disneyland Resort in Anaheim, California, opened on July 17, 1955.
It is the only theme park designed and built under the direct supervision of Walt Disney.
It was originally the only attraction on the property; its name was changed to Disneyland Park to distinguish it from the expanding complex in the 1990s.
Walt Disney came up with the concept of Disneyland after visiting various amusement parks with his daughters in the 1930s and 1940s.
He initially envisioned building a tourist attraction adjacent to his studios in Burbank to entertain fans who wished to visit; however, he soon realized that the proposed site was too small.
After hiring a consultant to help him determine an appropriate site for his project, Walt bought a site near Anaheim in 1953.
Construction began in 1954 and the park was unveiled during a special televised press event on the ABC Television Network on July 17, 1955.
Since its opening, Disneyland has undergone a number of expansions and renovations, including the addition of New Orleans Square in 1966, Bear Country (now Critter Country) in 1972, and Mickey's Toontown in 1993.
Disney California Adventure Park was built on the site of Disneyland's original parking lot and opened in 2001.
Disneyland has a larger cumulative attendance than any other theme park in the world, with over 650 million guests since it opened.
In 2011, the park hosted approximately 16.14 million guests, making it the second most visited park in the world that calendar year.
According to a March 2005 report from the Disney Company, there are 65,700 jobs supported by the Disneyland Resort, which includes, at the Resort itself, 20,000 direct Disney employees and 3,800 third-party employees (that is, independent contractors or their employees). 
Swiss Family Treehouse is an attraction that features at several Walt Disney Parks and Resorts.
The remaining versions based on the original are located at Magic Kingdom Park, Tokyo Disneyland and at Disneyland Park in Disneyland Paris.
The walk-through attraction is centered around a giant treehouse where everyone can hear and see various scenes based on the Disney film "Swiss Family Robinson". 
Before he wrote the book called "Swiss Family Robinson", Johann Wyss and his kids imagined what it would be like if they were stranded on an island.
So together, they came up with lots of crazy adventures for the Robinsons.
Almost two years after the Disney film "Swiss Family Robinson" was released to theaters in 1960, Disneyland introduced the "Swiss Family Treehouse" to Adventureland.
When the Magic Kingdom opened at Walt Disney World Resort on October 1, 1971, the "Swiss Family Treehouse" was one of the original attractions of Adventureland.
The tree, while intended to look real, is actually made up of steel, concrete, and stucco, stretching tall and wide.
Yet, it looks exactly like the one in the movie.
Similarly, when "Euro Disneyland" (now Disneyland Park) opened on April 12, 1992, it featured a version of the attraction located in Adventureland, named La Cabane des Robinson.
Tokyo Disneyland also has a Swiss Family Treehouse, a late addition to the park; not opening until 1993.
In 1999, the original attraction at Disneyland was closed and reopened the same year as "Tarzan's Treehouse."
The Disneyland Dream Suite is a luxury apartment located in the New Orleans Square area of Disneyland Park at the Disneyland Resort.
It was created as part of the "Year of a Million Dreams" promotion that ran from October 1, 2006, through December 31, 2008.
