There is a military discount of -40% off rack rate (published rate) at every WDW resort. Just call the WDTC and they will book the discount for you.
Here are the details from
www.Mousesavers.com:
Military Package with Dining
Special deal for eligible members of the US Military*:
A discounted Military Package with Dining is available for stays most nights through 9/30/10. The Military Package with Dining does not include tickets because there is a special ticket offer for military.
The package includes a room discount of 40% off, but the Dining Plans are priced at the regular rate.
The Military Package with Dining is subject to regular Walt Disney Travel Company package rules.
*Offer available to active duty military, activated reservists and retired military. Proof of Military eligibility is required.
Request code OUR for package with Quick Service Dining Plan, OUS/OUT for package with regular Dining Plan or OUU for package with Deluxe Dining. (My note: This is a slight change from 2009 as the DxDP was not included when the promo. was announced. I believe some reported being able to get it added later-on in the year, but I'm not certain.)
