Hello Shannan!
We love using Disney's Armed Forces Salute for discounts on Walt Disney World Resort rooms! And you're going to love the
Villas at Disney's Wilderness Lodge! Make sure you check out Chip n' Dale's Campfire Sing-a-Long if you get the chance!
You are correct in that the Magic Your Way Stars and Stripes tickets must be purchased at the Shades of Green Resort. If you will not have access to a vehicle on property, I suggest taking the boat over to the Magic Kingdom Park and hopping on the Resort Monorail. Exit at Disney's Polynesian Resort and then you'll be able to walk across the street to Shades of Green. Make sure to have your military ID on you!
As far as my experience has been, we have not been able to add Stars and Stripes Magic Your Way Tickets to our Key to the World Card (KTTW), however we still use our KTTW for charging privileges and for identification during Extra Magic Hours!
Depending on the length of your vacation and your travel dates, you may also have the option of using Disney's Armed Forces Salute tickets. These are four day Park Hopper tickets to which you can also add on the Water Parks and More option for an additional fee. More information, including pricing and block out dates, can be found at the
Armed Forces Salute Special Offers page. These can be purchased at any ticketing window as well as at Guest Relations in Downtown Disney. They are also available tax-free at Shades of Green.
I hope you have a most magical vacation, Shannan! Please come back and visit us if you have any more questions!
