It really is. And way too random to plan for, if that's what you are trying to do. Or to try and avoid, if that's what you are trying to do.As you see from the responses above, there really isn't one solid answer. I don't think any ride breaks all the time or consistently (yes, I know FOP had issues when it first opened, but I'm talking long term patterns). Some are weather dependent, like TT. But over the years, I've experienced a ton of rides that go down from time to time. Got stuck on Pirates once and had to be evacuated. So I think the real answer is "it's random".
Broke down and restarted or evacuated?We were on Buzz Lightyear when it broke down and we got nothing.
why are you asking are you hoping to go an any time FP for FOP if so most of the time there is some restriction like you can not use it for those rides or you can use it for theses rides. and most of the time unless the ride you have is FOP or the river ride the pandora rides are not listed in the way time FPWhat rides most often end up going down and resulting in an anytime FP?
