As a military family you can stay at Shades of Green which is a VERY reasonably priced resort for what they offer compared to Disney resorts. Good location, balconies, larger rooms, cheaper restaurants than Disney resorts.
We have usually stayed at Disney resorts with the military discount. We are also going in Sept 2020! Usually I stalk every website/facebook page with military Disney info that I can until military discounts are released for Disney resorts. Usually at the end of Sept. They offer up to 30% on value, 35% on moderate, and 40% on deluxe. Last year I found that they mostly offered 35% off deluxe, not sure on the others. Call ASAP! Discounted rooms are extremely limited and will fill up FAST!
Depending on your family size and your rank Shades of Green may be a better, and cheaper option for you. If you are higher ranking then you may be better off at a Disney Resort. I recommend you decide what your room budget is and go from there!
They offer Military Salute tickets that are a GREAT deal! We like to order them ahead of time from Shades of Green because they will mail them to you already activated and you won't have to stop by guest services to activate them before entering the parks.
They also offer a discounted PhotoPass. I believe it's $98?
If you use a military room discount at a Disney Resort you can not get
free dining or any other discount BUT you can add the dining plan to your reservation and it would be considered a package, so a $200 deposit. You would just add your salute tickets to your account once you got them. (You can not get the
Disney dining plan if you stay at Shades of Green.)
Hope that helps a bit! Feel free to send me a message if you have any other questions! We have gone to Disney World three times with military discounts and have stayed at Disney resorts and Shade of Green!
