I also debated whether to purchase memory maker. I had my own camera, would we see many of Disney photographers? , was it worth the money? I was so glad i bought it. . We had tons of pictures to choose from and Picts of our entire group that i would not have had without it. Would definitely do it if you have kids.
And they did take photos during the enchanted tales show plus at the end each child got to pose with belle
Also there are cameras on many rides that capture action shots and photo opportunities when meeting different characters
