No matter what I do and how much I stress, I always stick with Dsney property with the military discount. I couldn't even give in to Shades of Green, because you still have to pay to park there as well as at the parks, because I don't like their buses.
AFVC or Armed Forces Vacation Club has some great rates $349/week, sometimes even $299/week, but you would still have to pay for parking and then you give up Extra Magic Hours, which are important to us. Maybe someday, because you can't beat a 1br, 2br, or 3 br for $53/night.
