I was about to say I don't think modern Disney cares. They'd rather just leave the attractions either running in awful condition to continue to eat up guests (poor show) or they leave them empty and abandoned in plain sight (even poorer show tbh) until they get another popular IP and force it into one of those spots. I would much rather a ride only operated some months out of the year but in excellent condition rather than being open every day in awful shape.
You're talking about a long past era when Disney Parks had off-seasons and would be closed certain days a week, such as Monday and Tuesday.
I recall when I was a kid some attractions like Carousel of Progress at WDW would be closed "seasonally" despite the parks being open 365 days.
As another poster mentioned that is something that WDW would do, this is the Disneyland forum however and the question was put into that context.
Keel Boats was another attraction that saw fewer and fewer operating hours toward its end. That was back in the days when DL had “off” seasons of much lighter attendance. Fantasyland Autopia was redundant and rarely needed (though it was always nice to see it in operation) and Mission to Mars simply wasn’t very popular toward its end. They were the exceptions. Columbia Sailing Ship is the only one currently at the park I might put in that category, but, again, it’s a non-typical situation where it’s also a nighttime show element. I can’t think of any other current ride Disney would take offline for non-maintenance/refurb purposes.
