Well, normally I'd agree, since I've only been to Disneyland Resort four times... granted they were for about 4 or 5 days each, but only four times. But I'm one of the few who looks at every tiny detail in the park. I notice when the same music is playing. I notice the different style of trash cans. I notice the peeling paint and the cracked sidewalks. I notice the lighting and the changes that occured since I was last there.
It is entirely true that Disneyland Park has gone way up in the past five years. It's also true that the Magic Kingdom has gone down for the last ten years. It's not just in terms of park upkeep, it's also in terms of the Cast Members. Wether you like it or not, Matt's idea for the attendance policy for CMs in Disneyland has worked wonders. The only ones left are the ones who care about the park and are happy on a daily basis. Hardly the ones that will call in sick weekly and be snoody to guests daily.
The point is, right now, Disney World will hire ANYONE to work. And since WDW is on an older CDS that doesn't require as much attendance as DL's system, the CMs don't seem to care as much in various places. It's a noticeable difference. And you don't get these crazy excuses from CMs about "ruining the magic" over at Disneyland. They use their common sense over in Disneyland, something that is just not present as much in the MK. The upkeep of the parks is a tad better in DL. But that is not the main difference. Disneyland Park has about twice as many attractions that the Magic Kingdom Park has. And the repeats are almost always better over in Disneyland. Not because it is the original, but because they are being updated left and right there. The theming is better, and the park just looks amazing at night, moreso than WDW's Magic Kingdom.
