There are few sites that serve both font geeks and theme park geeks. This massive Disney fonts list is one. Want to know which font is used in the logo for Mickey's Star Traders, or which font is included in the posters for the Haunted Mansion? How about the old Epcot logo font or the font used in the Magic Kingdom guidemaps back in the '70s? It's all here including links to purchase the fonts or find freeware alternatives. Wow.
Strangely, this very topic was discussed at Typographica today.
