WDW Annual Passholders can get special discounted rates at select Walt Disney World resorts for check-ins 8/28/05-10/4/05. The code gives you a flat discount off the rack rates: $18 off Value resorts, $45 off Moderate resorts and $70 off Deluxe and Home-Away-From-Home resorts. Some sample rates:

* Animal Kingdom Lodge - $129 standard, $210 savannah view
* Boardwalk/Beach Club/Yacht Club - $224 standard
