Hi Suhaill,
Thank you for visiting the Disney Parks Moms Panel with your question.
The Four-Day Military Promotional tickets, also sometimes called the Armed Forces Salute tickets, are a great way for members of the military to go to the theme parks. There is a limit of six of these tickets per military member. Good information on Walt Disney World
theme park ticket and other discounts for the military can be found online. Another good site with information specific to the military and Walt Disney World is militarydisneytips.com. On this unofficial site, there is a lot of information for military families visiting Walt Disney World. For further information on purchasing your tickets at Shades of Green, I suggest calling the resort at 407-824-3400 and asking to speak with the ticket office there.
Another option for your brother since he is a Florida resident is to look into
Florida resident discounts for Walt Disney World theme parks. There are often great deals that he can take advantage of on theme park tickets due to his Florida residency.
Have a great time at Walt Disney World, Suhaill. Please do not hesitate to ask if you have any further questions.
