Hi Elana!
Walt Disney World appreciates our
Military -the deals that are currently being offered for the Military are absolutely AMAZING!!! The deals at the hotels are good all year long, with the exception of a few days in June and November. As far as I know, the discounts are based purely on availability. Also, it appears that as long as the discount is available at that time, that most hotels are participating.
It appears that the best deals (up to 40% off!) can be found at the moderate resorts; however, others are available. For a party of your size, I recommend either getting two connecting rooms at a Moderate Resort, or a two-bedroom villa at one of Disney's Home away from Homes. Last year, we were pampered by all of the space that we had in a two-bedroom unit at the Saratoga Springs Resort. We could even walk to Downtown Disney!
The folks at the ITT office on your base will have more details and can even book your trip for you!!!
Much pixie dust,
Jackie S.
