Hi Dana,
I'm glad to have been of some assistance to you in your Walt Disney World vacation planning!
In order to answer this question, I consulted another of our brand new 2012 Walt Disney World Moms Panelists,
Ashley F., who is also a Military Wife. She was able to share some additional information to help me answer your question.
Guests who are staying at Shades of Green unfortunately do not get to participate in some of the perks that Guests of the Disney Resorts have access to, such as the Disney Dining Plan, Keys to the World cards with charging privileges, free Disney Theme Park parking, etc...
However, they DO get to participate in the Extra Magic Hours available to Guests of the Disney Resorts! This is a great perk, and one that will give you plenty of extra time in the Parks to enjoy many of your favorite attractions, entertainment, and characters!
I hope this is helpful! Have a wonderful time!
