Memory Maker is a 100 percent digital option, and allows guests to download unlimited digital photos of Disney PhotoPass pictures, without having to purchase the photos individually.
With Memory Maker guests receive digital copies of all the photos for one price ($149 if purchased at least three days before a Walt Disney World vacation, or $199 if purchased in the parks or resorts).
With the original PhotoPass option, guests receive a CD with their photos after their trip is complete. With Memory Maker, the digital downloads are available immediately and photos can be viewed, downloaded, and shared as often as guests want, provided the photos are still in the guest’s My Disney Experience account.
As with PhotoPass pictures, the Memory Maker photos will have a 45 day expiration period, after which no more photos can be downloaded.
