I was hoping there would be a thread like this on here. I will need to post something similar in the WDW forums, but this is a great place as well. After spending 5 days at the Disneyland resort last week, I do have a "renewed" appreciation for WDW as well. I guess with my second visit to the Disneyland Resort, I noticed that even here, in Walt's Magic Kingdom, things break, wear out, get rundown, etc...and it's not really a big deal, not even at WDW.
At Disneyland, I noticed paint and stucco on the ceiling in the queue to Splash peeling off (when someone starts, I guess everyone else just follows), lights burnt out on Main Street Marques, some of the geese in IASW not quacking, TONS of rust on the IASW show building (that building needs a serious exterior rehab), the Hats Pirate in PotC not shaking his hats like he used to, lots of chipped paint as mentioned in Toon Town, the Columbia in need of new paint job (I assume it's coming after the Mark Twain gets done). And Alice in Wonderland is truly an eye sore both from the ground AND from on the ride.
Anyway, the point is, with 16+ Million visitors every year and operations most days of 16 hours, things are going to get warn out/break, etc. I think the difference is how long things stay broken at WDW vs. DL and what makes an attraction "not show ready." These are the things that we deal with at WDW that I don't think you DLers have.
