Fans of old-school Disney magic will want to plan accordingly: the Carousel of Progress at Magic Kingdom has officially closed its doors for what's being described as major changes to the long-running attraction.

The ride, which traces the story of American family life through the lens of technological progress across the decades, has been a fixture at Magic Kingdom since it debuted at Walt Disney World in 1975 — and before that at the 1964 World's Fair.

Details on exactly what updates are planned or how long the closure will last have not been announced, so guests hoping to catch the classic "There's a Great Big Beautiful Tomorrow" show should check current park schedules before visiting.
