Hello Deb, welcome to the Disney Parks Mom´s Panel!
We still do not have much official information on
Disney´s Memory Maker, but we do know that it is a digital only entitlement.
I have read that Memory Maker is replacing PhotoPass+ and guests who already purchased PhotoPass+ can change to Memory Maker at no additional cost. Memory Maker will probable include all available photos available with PhotoPass+.
I also read about new videos of digital experiences with Disney Characters that will be included in Disney´s Memory Maker.
For up to date information, I suggest contacting PhotoPass Guest Support team at disneyphotopass_support@disneyworld.com or at (407) 560-4300.
Thank you for visiting and we hope to hear again from you.
Miguel
