Suggestions..
Hi there,
Last fall semester, I completed 3 independent studies on Walt and the Disney company at large. To give you an idea on my suggestions, I studied 3 areas: (1)Development of the Florida Project, specifically the Reedy Creek Improvement District; (2) The inital EPCOT concept, with a comparison to the Celebration, FL experiment; and (3) An internship overview of my time as a College Programer, mostly about the sociological aspects of the Disney Parks (mostly MK) and historical representation in the parks. All 3 papers were about 20-30 pages in length, so I have more sources then are listed.
Here's a list of my best sources (All have background on Walt and other projects, and they are in order of helpfullness):
(1)Vinyl Leaves: Walt Disney World and America - Stephen Fjellman
(2)Married To The Mouse: Walt Disney World and Orlando - Richard Foglesong
(3)Disney and His Worlds - Alan Bryman
(4)Celebration, USA - Douglas Frantz
These are just 4 books to get started on, and since its only a 15 pager, these and any number of books will get you there.
If I can be of any other help for sources and such, just let me know. Good Luck on your paper!
