I think the disconnect here is that we all expect very high standards from Disney. I know I expect lights to be out at UNI or Six Flags etc.., but I expect more from Disney. I want the "plussing" that Disney used to offer, so for me and many others, large expands of light bulbs out for long periods of time is very disappointing...
I think this is it.
I like chaser lights on coasters. Six Flags Over Georgia used to have them on the Mindbenders and the Great American Scream Machine. 30 years ago they consistently worked. Then, as they repainted the rides, they didn't seem to remove the lights to do it but left them on and spray painted away. Sometimes the bulbs would have paint. Sometimes they wouldn't. As time went on you just sort of shrugged your shoulders and thought, "Yeah, that's Six Flags," in a disappointed sort of way.
Eventually they had sections of the chaser lights fail so if you had a sequence of lights, 1-5, and that made the chaser part, then say, sequence 2, all the way through the entire string of lights, failed and they never fixed it. So you ended up with chase-dark/pause-chase-chase-chase. Eventually other sequences failed and you had something really stupid like: chase-dark-dark-dark-chase.
It never got better. It only got worse. At some point in the late-1980s or early 1990s they simply lost the initiative to fix them.
None of that even accounts for bulbs that were out that they wouldn't replace. It really looked like crap.
Of course you could argue: but the coaster functioned the same and it still left the station, went through the circuit, and came back. Yep. It all worked the same. It was still disappointing and a bit of an eye-sore with the lights as the years wore on.
They eventually removed the chaser lights from both coasters and now they're just dark with maybe a few flood lights on them. The traditional, neat effect is lost, though. I really wish someone would make the decision to bring them back in LED form (they'd still need to maintain them and not just spray over them when painting the ride).
It kind of comes down to this: If you're running the park do you give a crap?
If you don't, you end up like Six Flags.
Over the last 5 years or so the management at Six Flags seems to be trying to make things better. The park is nicer. The employees are nicer. The park is cleaner. There were a good 10-15 years of crap-everything that left a bad taste in a lot of people's mouths. It's easier to keep a customer with quality, than it is to lose a customer and to try to win them back. Lots of people stopped going to Six Flags because it became so crappy.
