Also, don't forget that with MemoryMaker, ride photos are not added automatically. For attractions that have on-ride pictures (e.g., Expedition Everest, Space Mountain, Splash Mountain, RnR, Buzz), you'll need to stop at the viewing area after the ride, write down (or remember) the number of the photo in which you appear, and the stop at the cash registers for the accompanying photo purchase location/gift shop and ask them to add the photo to your MemoryMaker account. If there's nobody in line in front of you, it only takes a few seconds for the CM to pull up the photo and scan your MagicBand. Of course, having people in line ahead of you, poking around trying to order photo prints, can bog you down bigtime, so I learned to dash to the screens, take a quick look at the number, start mumbling it to myself repeatedly, and then hurry to the register so I could be in-and-out first, long before the rest of the crowd -- who were typically writing down their photo number or having a CM write it down for them -- got there.
(If you forget to have an on-ride photo added, you can call and try to have them find it for you later, with a description of when you rode and what you were wearing, but it's much, much easier and more fool-proof to have them added as you go.)
