Hi Nichole,
Thank you so much for visiting the Disney Parks Moms Panel with your question. There are many intricacies in military tickets for Walt Disney World. Let me give you some thoughts here that should help you to get to your answer.
It seems that the best ticket deal for military members is the
4-Day Military Promotional ticket. These tickets are $169 each and include park hopping. A military member can purchase up to six of these tickets. However, currently this promotion runs through September 27, 2014, so these tickets would not work for you since your travel dates are after this date. Disney has renewed this promotion in the past; however, I do not have information as to if they will renew this again. You would need to wait for tickets which will be valid for your stay to be released.
There are other discounted military tickets available for Walt Disney World; however, they do not offer as large a discount as the 4-Day Military Promotional tickets. I have found the unofficial website militarydisneytips.com to be a great resource in looking at ticket options for military families. If you visit this site and search for "regular Disney ticket discounts," there is an article that will help you to navigate those options. Another option is to call 407-824-1403, which will get you to Shades of Green's ticket office, where they can also help you with military ticket options.
I hope that this information is helpful for you, Nichole! Have a wonderful time planning your trip, and please do not hesitate to ask if you have any further questions.
