Download the Shop Disney Parks app then search Autograph. You will be able to see all of the books available then see exactly what store has it without wasting time wandering around. I highly recommend an autograph and photo book so you can print a picture of her with each of the characters to go along with the autograph. It will help her keep the memories when she's older if she can see the photos. I just checked it and Curtain Call Collectables has both princess books, the Minnie Mouse book and many more. If you go to the right on your way in it is just after you go under the train tracks on the right. Much smaller than the Emporium and will be a faster stop for shopping and getting on with your day. They also sell books at the carts outside just as you pass under the tracks on both sides but the selection changes. Have a magical day with your niece!
The emporium has many different faces to their autograph books. You will have to walk around to find them all, but it will have the best selection. I really liked the look of the 2019 blue autograph book. It is on the wall with the 2019 shirts.
