Hi Christina!
You've uncovered one of the many unique ways a Walt Disney World vacation is like no other ... special "magic" shots in your photos!
Disney PhotoPass photographers are scattered throughout the Parks to capture memorable moments for guests, and often times can magically include light sabers, balloons, Tinker Bell, Captain Hook, Simba, Sebastian and more. A very comprehensive list exists over at one of my favorite unofficial fan sites, allears.net. Simply search, "Disney's PhotoPass" and scroll all the way down to "magic" poses. Here, you'll find a great list of locations and characters but keep in mind PhotoPass options are always subject to change, especially with the technological advancements of MyMagic+.
One of my favorite purchased magnets permanently affixed to my refrigerator is that of my kids holding Tinker Bell. They couldn't believe their little eyes when they saw the finished product ... pure magic.
Best wishes, Christina, and please visit us again with any other questions coming to mind.
