Try searching some old posts.... some guests DID meet and get an autograph from Tink last fall. It was a practice run, from what they said. She was in Toon Town, I think...
I was desperate to find her myself. My DD8 was dying to find her. Our next trip is October of this year. I have been praying that the fairy movie is out and that she could meet some of the fairies form Pixie Hollow for her birthday (which is while we are there). I'm sure our fellow members will keep us posted!!
