@Montanabel you are correct. You pre purchase Memory Maker for $149 at least 3 days prior to your trip. Your memory maker is activated upon first use in the parks and you have a 30 day period to collect as many pics as possible at any of the 4 parks, special events or character dining. You also get one ride photos at no extra cost, magic shots (with disney characters inserted) and animated magic shots. The icing on the cake is that you get on ride videos
Once you get home you have a window of time (I think it's 14 days) to download your pictures to your PC. You can also add borders and stuff as well but make sure you download the originals first. Once your downloaded the files you're free to reprint anyway you like for personal use.
I'm planning on using ours to create a coffee table book. We create a new book using snap fish after each holiday we take
