This is a tough one to defend disney on, but I gotta. first, it is rare that you can every get a large group of people to all tell the same story. Its just a matter of human physics. I bet you could call enough times to Disney and find someone who tells you that the Barnstormer is open.
It is the fact that to us WDW is a passion and we know every nut and bolt. To many cast members it is a job. Sure they may be good at it, but talking to those of us who would be great makes them look dumb. Especially when someone comes up with a question that is not commonly asked. I bet the monorail hours question is not that common.... either you already know about it, or you wouldn't know enough to even ask.
Finally, tell us it needs fixed. First they did. Second, they are not going to release a press statement (or any statement) that says Come Down to Disney World!!!! We got some stuff to fix. As much as you want them to they will not brag about fixing things that are broken. When was the last time you heard Disney refer to any of the changes to the Tiki room and repairing the fire damage. Nope, they simply announced that it was closed for refurb and returning the show to the original. It is all corporate spin. Nothing more, nothing less. Keep expecting more and you will be disappointed.
I will also add that Disney also looks at the parks much different than you or I. They see the parks in 1 week per year or 1 week per several year increments for the guests. While you think that closing the beam for a couple of months at a time is no big deal, they see that as hundreds of thousands of guests who will not get to experience one of the marque rides in the parks. They won't care if it is open next week, since they won't be there next week.
