The Orlando Sentinel said Sunday that Disney reported the death as part of a quarterly injury report. Florida's big theme parks have an agreement with the state to report guest injuries in exchange for avoiding state ride-safety regulation.
The report indicated the woman had a pre-existing heart condition before she rode the Prince Charming Regal Carousel.
Walt Disney World reported two other injuries in the fourth quarter of last year. A 71-year-old woman broke a hip and shoulder after riding the carousel and a 76-year-old woman injured her leg after falling on a moving platform for another ride.
No other parks reported injuries in the quarter.
