Hi Ashlie,
Thank you so much for your question. Your Armed Forces Salute military discounted tickets can be linked directly to your My Disney Experience. Once you open your
My Disney Experience, go to the "My Reservations" section, and under Tickets and Passes you'll be able to link tickets. Now, these will be linked to your account, but you will still have to take your vouchers to will call to be scanned and fully activated.
While you don't need any official documentation that your child is under 2, it is nice to have a copy of her birth certificate. The last time we took our little girl to Walt Disney World, I kept a copy of her birth certificate in her diaper bag, just in case any cast members asked for documentation. Better safe than sorry, right?
I hope this answered your question, Ashlie. If you have any other questions before your vacation, please feel free to ask us at any time.
Have a fantastical Disney day!
