This month in Disney history is the big one: on October 1, 1971, Walt Disney World opened its gates — and this October, it turns 55.

Opening day

Day one was a remarkably small version of what exists now: the Magic Kingdom, plus two hotels — Disney's Contemporary Resort and Disney's Polynesian Village Resort. Crowds were light that first morning; the real rush came later. From those three buildings grew the four parks, dozens of resorts, and the whole vacation kingdom we know today.

Why it's called Walt Disney World

Walt never got to see it — he died in 1966, years before it opened. His brother Roy O. Disney came out of retirement to finish the project, and he insisted it be called Walt Disney World, so that everyone would always know whose dream it was. Roy read the park's dedication at the base of the Town Square flagpole on October 25, 1971.

Disneyland was Walt's. Walt Disney World was Roy's gift back to his brother — right down to the name.

Why this one for October

Fifty-five years on, the dedication plaque is still there in Town Square, and October 1 is still the resort's birthday. It's a good month to stand on Main Street and remember it all started with one park and two hotels.
