Hi Kim!
First, let me thank your son for his service. Our family has used the Armed Forces Salute tickets several times. It's an amazing program and we're so thankful for it. Have you considered adding the Water Park Fun & More Option to the tickets? You'll not only have four days at the theme parks, but you'll also have four entries into Disney's Blizzard Beach and Typhoon Lagoon Water Parks, DisneyQuest, and more! You could also build in some days to explore other resorts, try out some
recreation options, or visit Downtown Disney.
If you want extra days in the four theme parks, you can head over to Shades of Green to purchase discounted Magic Your Way Stars and Stripes tickets. The discount isn't as significant as the Armed Forces Salute, but it's still a great savings!
I hope this helps! Please feel free to follow-up with me if you have any other questions, Kim.
Have a magical day,
Ashley
