Step-by-step explanation:
Walt Disney World was officially opened on October 1, 1971. The opening day speech was given by Roy O. Disney, the brother of Walt Disney. Roy was instrumental in the realization of the Florida Project, which was the code-name for what would become Walt Disney World, following the death of Walt Disney in 1966.
The park was dedicated to the ideals, the dreams, and the hard facts that have created America, which was a sentiment echoing the legacy and vision of Walt Disney himself. The opening day speech by Roy O. Disney was a significant moment as it marked the culmination of years of planning and development. It is also a touching tribute to the memory of his brother, who had envisioned the park but passed away before its completion.
The opening of Walt Disney World Resort expanded on the concept of Disneyland in California and has since grown into the most visited vacation resort in the world, with millions of guests annually experiencing its theme parks, water parks, and numerous other attractions.
