I get far more full family photos now than I ever did before PhotoPass. All my WDW photos as a kid were with me, my sister, and one of my parents (with the other taking a picture). Sure, we got the odd photo where we were able to get someone else to take a picture of all of us, or a cast member happened to be walking by (which wasn't often the case on Main Street, for example). But most of our pictures were three out of four of us.
Contrast that to today. We still take pictures with our phones, lots of them. But we don memory maker, and I got hundreds of photos of my whole family. That's the value Memory Maker has for me.
