It's funny, how many people you overhear at WDW referring to the MK as 'Disneyland'. I wonder how many of those people have never visited the real DL to see the difference. I also wonder how many of those people have visited both, and still don't discern the difference.
DL has a charm, history, and overall feeling that the MK will never capture. I know most of that is because it was designed to accomodate many more people, but to me it feels like something else...the fact that Walt never walked thru WDW's big fiberglass castle.
Don't misunderstand me, I love the MK. I just see it as a very different place than DL. Even though it's a pain to get to, there's something special about having to catch a monorail or boat and feeling the anticipation build as you approach. There are some small touches like the Castle Rose Garden that we love. It's also nice to visit some old favorites, like the Country Bears, Swiss Family Robinson Treehouse, and (hand on heart) the Carousel of Progress. I like their Splash Mountain (but it needs some TLC), and I always felt like if you could combine DL's superior Space Mountain track with some of WDW's lighting you'd have a real winner (and it sounds like my wish has now been granted).
But the 'Cliff's Notes' version of POTC, the lack of attractions and theming in Fantasyland (especially no Toad), and no New Orleans Square always take me a little aback. Main Street is one long shopping mall. Toontown Fair still looks like the temporary area it was supposed to be. And one visit to the Tiki Room "Under New Mgt." was enough for me.
So, in short...if I have to choose, it's DL every time.
