A few of my favorite things...
Everyone seems in agreement on what makes the Magic Kingdom, well... so magical! I love the music and have almost every little bit of info that I was able to glean off of KaZaA.
For more specific loves:
1. The orange smell in Horizons "orchard of the future" scene was one of my favorites. I went on the ride 20 times in a row to determine if I was actually smelling it or if my mind was playing tricks.
2. The ambient music around Living Seas, or on the general pathways.
3. Hidden Mickeys. During my last trip I was stuck in line of the Haunted Mansion and a mother in front of my group was having trouble keeping her little ones happy. Disney just let's me open up to people so I informed her about the Hidden Mickeys and showed them a couple of pictures of ones I had found that day. Soon I had the mom and kids in rapt attention, all of them discussing how "they were going to find those Mickeys!" They said I made their day... And I'm not even a CM!
4. Finding a secluded spot in Animal Kingdom where no one else is around. Or barring that, standing on the bridge leading to Dinoland and look out at the Asia section. Sooo beautiful.
5. When they had the DDR machine in the Pizza Planet at MGM, I would play all the songs on Trick Mode and attract a HUGE audience. I had people camcording me!
Darn it, now I want to go back!!!! Aaaagghh!
