Hello Rachel!
Welcome back to the Disney Parks Moms Panel! I am a big fan of
Memory Maker because of the value and convenience it adds to our family vacations. Memory Maker is going to be a particularly good value for you because one Memory Maker will indeed cover both of your trips!
Once you download your first
Disney PhotoPass photo or otherwise activate your Memory Maker purchase, you will then have 30 days to capture more photos and videos at
Walt Disney World Resort. All of your Disney PhotoPass media from within the 30 days will be available to download until that media expires. This means that one Memory Maker purchase will cover both of your September 2017 visits. Hooray!
Quick Tip: Keep in mind that your PhotoPass photos and videos expire 45 days from the date they are taken, so be sure to download them before they expire.
I hope this helps with your planning, Rachel! Please let us know if you have any additional questions about your upcoming visit.
Wishing you many magical memories!
Erin
