I'm not sure where you can see Tinkerbell but make sure she doesn't miss this opportunity:
Waking-up Tinkerbell
If you are among the first to enter Tinkerbells Treasures shop (to your left as you pass through Cinderella Castle), your kid(s) may be in for a special treat. Ask the Cast Member if you can wake-up Tinkerbell. The kid(s) are given a sword (for boys) or a wand (for girls) and are instructed to tap on a small chest three times and say wake-up Tinkerbell. Sure enough Tinkerbell wakes-up and flies around the room in a dazzling display of lights and sounds. The helpers are usually given a certificate that proclaims that they helped wake-up Tinkerbell. If you miss this morning ceremony, Tink typically flies around the shop intermittently through out the day.
