What really gets me going is talking about it to my family and my closest friend (who is also a Disney nut, closeted, but a nut nonetheless...).
I like to learn about all the "little" things that make Disney so special. The lore, the history, the little fun facts about the rides. It really makes me appreciate what they do down there - it's much more than a theme park. The designers and Imagineers think of EVERYTHING (well, except for maybe Stitch's Great Escape...) before they do it and it really helps you become immersed in the magic.
Watching my favorite movies doesn't hurt either... just picked up the Ugly Daschund the other day. =)
