I had the privilege of living ~20 minutes away from Disneyland when I was a kid (always saw the fireworks from my home ^_^) and I loved every trip we made to the most magical place on earth.
The Haunted Mansion is my favorite ride ever. Ever! Even have the book on it. :P
It's one of the reasons of why I loved Epic Mickey so much... there were so many wonderful references to the theme park (I even noticed that the Lonesome Manor has the same spooky wallpaper as the Haunted Mansion. Yes, even the slightest details in that game didn't go unnoticed!)
Now that I'm living in North Carolina... It's been a while since I've last been there. But the whole family did make a trip to Disney World in Florida. We went to MGM (good), Animal Kingdom (awesome), and the Magic Kingdom (also awesome) and I'm bummed we missed Epcot. It was great... but interestingly enough I like the Magic Kingdom of Disneyland more than I did Disney World (Old Southern Plantation Haunted Mansion > New England Gothic Haunted Mansion). :P
So yes, Disneyland rocks my socks. I really want to go to Disneyland Paris so I can ride their Haunted Mansion. From what I've read, it's set in the old West (since it was put in Frontierland). Seems really great.
