I thought the same thing in April.
My wife and I both took notice of the strange occurrence of maintenance issues. We have been many, many times as well and have never noticed such maintenance break downs.
We were taking our friends whom have never been to WDW before. One worked at
Disneyland at one point, and the other had never been to any kind of Disney park. We made a bee line for Pirates of the Caribbean, because, well, it's a crime to be 21 years of age and never have ridden that. And, of course, we've been bragging and preaching about how magical WDW is to her. Well, as soon as we arrive at the entrance, we're notified that Pirates is shut down for maintenance. They refused to give us a time in which the ride would reopen, but I checked for rehabs and there were none going on anywhere. So we head for Thunder Mountain....when we arrive, a CM stops us at the entrance to tell us there is maintenance going on and the ride is down...and we see people leaving the fast pass line entrance, so obviously that just happened. So then, we head towards Haunted Mansion. When we get to the line, it's backed up further than I've ever seen it, and the CMs at the line tell us that someone has collapsed inside, and that it will open again momentarily.
Okay, so the last one isn't a maintenance issue, but still. At this point, our friends are saying "Oh yeahhh...realll magical." Our first three attempts at three STAPLES of this park are down.
So at this point we are determined to find SOMETHING. We head over to Tomorrowland and snag fastpasses for Space Mountain which IS running. We then go to Stitches Great Escape to pass the time. (Yes, we actually enjoy that ride...though I think we're the only ones on this forum that do. Alien was far better, but I don't think it's bad). The ride is running, but when you get in the part where you're locked in your seat and Stitch shows up, one of the robot machine gun arms isn't working! With only one working, the effects, sounds, and overall scene are just kind of screwed up.
Later in the trip we got on all three rides that were down. However, when we got on Pirates, once we went down the drop...it broke down. The boats backed up all the way from the exit to the bottom of the drop. We sat there for I'd say 10 minutes...then they shut the audio off for about 5 more minutes...then I'd say the actual ride probably lasted another 15 minutes because of the backup.
Then, we almost got stuck on Yeti on our last day. We rode it about 6 times in a row. The last time going up, the chains started making weird snapping noises and jerking a lot on the ascent into the mountain...then we just stopped for about 10 seconds right here:
then it jerked us up into the mountain. We decided we wouldn't push our luck and get stuck again and went ahead and made that our last ride.
I think there were a few other glitches in our experience. However, I'm not sold that Disney is slacking or anything. I firmly believe it was just a coincidence. It didn't ruin our trip, and I really dont expect it to happen again.
