Hi Eva,
Thank you for visiting the Disney Parks Moms Panel with your great question. I am a huge fan of
Memory Maker. I "may" currently have a few thousand photos in my account.
Once you have purchased Memory Maker, you are free to download your files as many times as you would like. Since you have purchased the photos, you are also given a limited licence to print your photos at home or at your preferred retail location. There is the option to print your photos directly from the Disney website, but I find it is a more expensive option. Personally, I prefer to upload my photos to a site like Shutterfly and have them shipped to my home. It's really convenient and I don't even need to leave my home!
Once you have purchased Memory Maker, be sure to ask PhotoPass Photographer for magic shots, they add so much magic to your memories! They have recently added an incredible option close to Mad Tea Party at Magic Kingdom Park, where you will be given a lantern to hold. This magic shot is only available during the evening, in order to get the full effect of the lantern.
I hope you have a magical time at Walt Disney World Resort, Eva. Take lots of pictures, those memories are guaranteed to last a lifetime.
Stephanie
