Hello Laurel!
Thanks so much for stopping by the Disney Parks Moms Panel! I hope you are having a magical week!
You can certainly order your PhotoPass+ as part of
Disney's PhotoPass® Service early. Just make sure it is ordered at least 14 days prior to your visit. Once you arrive onsite and have your first photo taken with your card is when the 30 day period for photos begins.
With PhotoPass+ you enjoy:
Unlimited PhotoPass photos in your account
The ability to customize your photos with fun Disney borders
Magic Shot photos
Photos from select dining locations
Photos from select attractions
Photos from other Disney experiences
I hope this helps and let us know if you need anything else as you plan your visit!
See you real soon!
