Hi Jennifer!
Thank you for visiting the Moms Panel!
The new PhotoPass+ is a great value, and now with the
pre-order special offer you can make even more great savings. It works like this - you must place your order for the pre-order PhotoPass+ at least 14 days prior to your vacation to ensure your package, including your voucher, arrives in time.
You then take your voucher to any of the Walt Disney World Service Sales Centers in any of the four theme parks to activate your PhotoPass+.
Once activated, you have a 14-day window in which to use your PhotoPass+.
I hope I have clarified this for you, but if you have any further questions, please come back and ask me!
