We love the plussing they did when they refurbed our SM here at DL. They took the time to really seal the cracks in the shell to get rid of light leaks. Then, adding the new track made all the difference in the world. The ride is extremely smooth and zippy - no more bone-jarring rattle! It's really ashame that many who are complaining about shutting down the WDW SM aren't looking at the long-term benefit of what they need to do to bring that ride back to the proper quality levels.
It's also interesting, from a demographics standpoint, to see how upset everyone is about the WDW refurb length vs. how everyone out here in DL took our year+ closure in stride. It really says a lot about how differently people look at their touring strategies and their attitudes toward the perceived value of their vacation when it comes to each individual park in comparison. I can see where the WDW folks are in it more for the "I'm spending my dollar on our vacation of a lifetime and they dare to close ....", rather than the "hey we're just hanging out at DL for the weekend - we can see it next time" types.
