8. It's easy
Check "get good pictures" off your list; this is the easiest to-do you'll encounter during your Disney planning. You can purchase Memory Maker prior to your trip online and link it to your My Disney Experience account. There are two options - an advance purchase option and an immediate start option. You will save a little money by purchasing Memory Maker at least three days prior to your trip. However, if you decide that you'd like to get Memory Maker while you're already in the middle of your vacation, you definitely have the option to purchase it at the parks, too.
