If your hubby has been activated any time since Jan.1, 2008 or will be activated to full time guard duty between now and the time you'll travel, you can get this deal. They will want proof when you check in. You said he will be activated to full time status soon, right? Will it be before you plan to go to WDW? If so, I would go ahead and book. You don't need proof right now, just when you show up.
