I don't have an answer for you but I had to share my autographed picture story, I hope you don't mind!!
After our trip in '99 I wrote a letter thanking Disney for the wonderful trip we had. I told them what a wonderful time we had at CRT and named a specific CM that was excellent. My 4 year old daughter wanted me to tell them how much she missed Mickey, so I did. Well, about 2 weeks later I received a wonderful letter from them thanking me for writing and included in this letter were 2 8x10 autographed pictures of Cinderella herself and 2 8x10 autographed pictures of Mickey for my dd's!! What a thrill that was!! I asked for nothing in my letter, it was just a thank you!! So I guess sometimes the less you ask for the more you get!!
