On one level you are correct. Now try having 40,000 slobs a day go tramping through your house and tell me how clean it stays, no matter how hard you try.
I also wonder about those rides that you listed. Dumbo... really? Should children not be considered at all? And having ridden the 7DMT just last week, I want to tell you that although short it is not a ride that any "kiddie" would do well on without an adult. Again except for the duration (which I'm pretty sure is longer then RcRC) it is not a kiddie ride and the intensity, although not through the roof, is on the same scale as BTMR and the swaying cars do add to it by quite a bit. I looked at a lot of things in the past week. Things that have been repeatedly been cited and complained about by all the gloom and doomers that frequent the boards. I looked for lights that were out, couldn't find any. I looked for ride components that weren't working. I found a couple, but, none that even slightly diminished the quality or overall enjoyment of it. I rode, in the front seat of Pirates and had the mist with the pirate, saw the swimming mermaids, got splashed on the drop, did not get held up even at unload and it was a busy day. Now out of all those things I will concede that even though I didn't get "soaked", I did get splashed more then I think is reasonable. Now for those with the argument that "it's a boat ride", so is Small World and I don't expect to get wet on it nor after all these years of operation do I expect to on Pirates. The public isn't laughing and reacting like they do on Splash mountain and Kali River. It is something that absolutely should not be happening on Pirates and hopefully with the six month rehab that is scheduled for it that problem will be fixed. We will have to wait to see on that one.
Other then that. The parks were exceptionally clean, I saw custodial crews everywhere I looked, with their white uniforms, brooms and dust pans and they were working. There were wonderful looking flower beds and well groomed trees and grass. I found the restrooms to be clean (not that I used everyone of them) and I too, because of an injury need to sit to get my knee and hip to stop hurting and never failed to find a place to do so.
Having just been there I am calling BS on a whole lot of the garbage that is being tossed about in some sort of righteous anger that is unjustified. I will also remind everyone that I am not a newbie, all smitten with bright lights along with smoke and mirrors. I have been going there for 31 years, as an adult, and I cannot remember a time, sans current construction projects, that WDW has looked better. It is possible that Disney has gotten the message because it sure seems different to me even down to the attitudes of the CM which has greatly improved.
It makes me sometimes wonder if those that are the most vocal about this stuff have been there lately or are they latching onto the perceptions of others as if they could not be wrong. Let me tell you it has been a long time coming that Disney actually got off their bonus enlarged rear-ends and decided to do something for the parks. Let's at least acknowledge what they are doing and not bury it under a pile of unsubstantiated verbiage designed to make themselves seem more knowledgeable then everyone else.
