You don't need to be there first in the morning, like the other poster said. You can see her anytime, you can see the light in the drawer, but if you ask the person working if you can see Tink, they will take you to the drawer and make her "fly" around the store.
Spoiler!!!!!!!!
Even when you wake her up you don't "see" Tink, she is just lights that move around on the walls, and in the drawer is just a light. My DD was dissappointed because she wanted to see Tinkerbell. She said "Mom, it's just a light, big deal!"
