The most critical event for Orlando's economy occurred in 1965 when Walt Disney announced the plans for Walt Disney World. The famous vacation resort opened in October, 1971, ushering in an explosive population and economic growth for the Orlando metropolitan area, which now encompasses Orange, Seminole, Osceola, and Lake counties. As a result, tourism became the centerpiece of the Orlando economy.

Orlando is served primarily by Orlando International Airport, though nearby Orlando Sanford International Airport also serves the area. Orlando Executive Airport is used for charter flights.

The Orlando area is served by one through railroad, CSX's A line (formerly the Atlantic Coast Line Railroad's main line), and some spurs, mostly operated by the Florida Central Railroad. Amtrak passenger service runs along the CSX A line.

The Walt Disney World Resort opened on October 1, 1971. It is the largest theme park resort in the world, although Dubai Land, twice its size, is planned to open in 2006.

On opening day, Roy Disney gave an opening dedication, after which he asked Walt's widow Lillian what she thought of Walt Disney World. She replied, "I think Walt would have approved."
