Hi Callen!
Thank you for bringing your question to the Disney Parks Moms Panel.
Disney Princess Half Marathon Weekend was my very first runDisney event so it holds a special place in my heart and I'm so excited for you to make some magical memories of your own!
I just returned from Disney Wine & Dine Half Marathon Weekend and looking at my race photos I am so thankful that I had
Memory Maker which includes all my runDisney photos! You will find on the course that there are usually a couple Disney PhotoPass photographers at various points throughout the race, plus a majority of the character stops along the way. They are also at the finish line to capture the moment you complete your race and after you are awarded your medal. I have the PhotoPass images in addition to my personal cell phone shots from my races and the quality difference is dramatic so it's something I would definitely recommend.
If you are going to be running plus spending several days at the park, Memory Maker is definitely the way to go. If you will just be doing the race, you'll be better just purchasing the single day of images. After you
link your images post race, you'll want to purchase this direct through the app. This
past answer should help you figure out exactly how to do that! This way you can also preview your images prior to purchasing them.
I hope you receive the royal treatment during the Disney Princess 5K! Please come back and let me know if you have any other questions.
