Fave attraction audio: The American Adventure. I wish they had the whole show's soundtrack out on CD. Not just "Golden Dream", although that is stirring in itself. I managed to get a few tracks around the turn of the millennium when they had a create your own CD feature near where Mouse Gear now is.
Ambiance music: the music in Canada. There's this one riff I really love. I thought I identified it as being from a song called "Peaceful", which I found out was a #1 in Canada for two weeks. But then I realized it was music from the soundtrack of the original O Canada 360 degree film.
Environmental sound: I'll go with some of the others on this thread and say the boat horns on 7 Seas Lagoon. Back in the early eighties, I was at Magic Kingdom with my pen pal, Nike, and to her, everytime the horn sounded, she said it sounded like the beginning of "Only Time Will Tell", by Asia, one of her fave bands.
personal fave thing to say: I usually come alone and don't tend to talk to myself. However, something I've often thought is that a lot of people save up big money to come here in a once-in-a-lifetime trip, and as a local annual passholder, I can come here just about anytime. I feel blessed and grateful.
