My husband was just saying that the Headless Horsman at MNSSHP is the best thing he's ever experienced at Disney (and, that was 3 years ago!). For me, two things that have surprisingly awed me were Talking Mickey at Disneyland (I don't think he's at Disney World - please tell me if he is!!!). I had such an amazing experience with him. I went to see him by myself and he created such a fun story about the Haunted House and had us pose as if we were hitchhiking ghosts. The other thing that has been a surprisingly fun experience is the Sorcerer cards. My son loves playing the game, but I love collecting the cards.
