Some time ago I took a trip to Italy. I'm walking through a museum in Florence and there is this cool marble statue. I stop and read the plackard. It is a 16th century reproduction of a classic Greek.
I find myself thinking, what? This isn't orginal, it is a knock-off.
Wait... a 500 year OLD copy.
Does Disneyland have problems? Of course. Walt didn't have the cash to buy thousands of acres of land.
No one had done a MK, so didn't know what problems. When they did MK, they knew to do a circular parade route, they knew to have cast walkways under the park. They had the money to do it right.
Does DL have flaws? Sure. For gawd's sake, you have to leave frontier land, go through New Orleans, and into Critter Country to get to the canoes, a Frontierland attractions...
Were they fixed in MK? Most.
But, MK is still just a knock off. An EXCELLENT knock off, but knock-off none the less.
As for which is the "flagship".
Ride count, DL wins hands down. Indy, Matterhorn, subs, Star Tours, Toad, original Tiki Room instead of aweful New Management. Okay, that is partially offset by Country Bear, Carousel of Progress, and Swiss Family.
Size of the castle, WDW wins.
So, in colclusion, if you like originals instead of knock-offs... if you like a big castle instead of rides... well then I guess MK is for you.
I like the original. I like the ride count.
Mostly I just like the 6 hour car ride for $100 gas instead of 5 hour flight for $1200+.(family of 4)
