Welcome to the DIS Family from IL!
As far as any discount codes, well, they can vary. An AP holder or Fl Resident can get about 40% off rack rates at times, and during the Deluxe hotels value season this can be a way to save the most since their rack rates are lowest then. Check out Mary's site:

For example:
Annual Passholder January-February 2005 Room-Only Discount Code
WDW Annual Passholders can ask for Code EWV and get special discounted rates at select Walt Disney World resorts for check-ins 1/2/05-2/16/05. Discounts will be extremely limited or nonexistent for check-ins 1/14/05-1/16/05, 2/3/05-2/5/05 and 2/10/05-2/12/05. Some sample rates:
Value Resorts (All Stars and Pop Century) - $49 standard
Moderate Resorts - $79 standard
Animal Kingdom Lodge - $109 standard; $151 savannah view
Wilderness Lodge - $109 standard; $126 woods view
Ft. Wilderness cabin - $144
Contemporary - $151 standard view garden wing
Old Key West - $169 studio
Grand Floridian - $259 garden view
Other resorts, room types and views are available at varying prices!
Valid Annual Pass required at check-in. Thanks to Small World Vacations for the info on this rate.
This is a good place to look around for any available discounts/codes you may be able to use. Also, it has the dates for the seasons (value season, regular season, peak season and holiday season)for all the resorts in Disney.
