Might not be the best thread to post this on, but this post form WDWInfo on "why we go", really speaks volumes.

I think that article is wonderful and is about as close as it gets to putting my love for WDW into words. But, as I read more and more about DL, I'm also starting to get really excited again. I'm seeing now that there are really cool differences. For example, I'm super excited to try the beignets from the Jazz Kitchen take out window in DTD for breakfast. That's not a possibility at WDW - I can't pop out of WL in WDW and grab a quick bite in DTD to take back to the room! That would be at least 1 hour round trip.
I'm also super excited about just walking to the parks from our hotel. I have walked from the Contemp to MK before. But, to have the ability to walk everywhere and even have an entrance directly to CA from the hotel is amazing! Having spent countless minutes (which added up over time now easily equal several hours) walking to, waiting for, then riding buses at WDW, I LOVE the idea that I am in complete control of how long it takes me to get from point A to point B.
Yes, I will miss Epcot. That's probably the one thing I'm certain I will miss. But, it's not like I'll never be in Epcot again. Plus, I've always thought it'd be cool to go on Soarin in California. And, now we'll get to do that. And...we'll get to do it with the whole thing completely re-furbished.
At the end of the day, I'm still nervous. But I'm getting gradually less and less nervous, and more and more excited to experience the differences, especially since I do believe I will keep that total immersion I get from WDW since I will never leave Disney property.
