Have you done PhotoPass before, at all?
Basically, with Memory Maker, you can take advantage of the PhotoPass photographers scattered around the parks. If you're unfamiliar with the process, well, it's easy - you walk up to one (they're typically in tan vests and have dSLR cameras either around their necks or on a tripod), they scan your Photopass card or MagicBand, and then you pose for a picture or two. They can make posing suggestions, but they can also take requests. (Though they're more likely to be flexible about poses when they aren't busy - if a photographer has a few families lining up, they'll usually keep things brief.) Ask for Magic Shots, if you're feeling silly/whimsical - those are special shots where the Photopass photographer will pose you a certain way, and after a sprinkle of pixie dust in the processing, you'll see a surprise addition to your photo. (One example: you pose holding up your hand as if you're holding something above your head... then you find a fistful of floating Mickey balloons in your photo.) Then, you're off again to enjoy the parks some more. Stop whenever you see a Photopass photographer and want a picture! Photos taken by any PhotoPass photographer will be included - the ones stationed by the "major" icons, the ones accompanying characters at meet & greets, the ones roving through the parks... Ride photos (for the rides that have photos) and special character meal photos (like the one with Cinderella at Cinderella's Royal Table) are included in the Memory Maker package.
All of the digital photo files will be linked to your account, so you can see them/edit them/download them when you get home. You can then share your images however you wish, on Facebook or other photo-sharing sites. You can burn them to CD, put them on a thumb drive, store them in the cloud, whatever. And you can print them wherever you like to print your pictures. (You have full permission from Disney to print the pictures at your convenience.)
My experience with PhotoPass has been pretty positive, overall. As the family photographer, I am rarely IN the pictures, so stopping for a few moments to let someone else snap the pictures puts me into the frame for a change of pace. I love it.
I will say that you get out what you put in, if that makes sense... if you don't stop for some photos, you won't have many to save/print/enjoy in the end. But if you're going on an anniversary trip and want to pause to capture some memories, together... it will do that for you.
