When we stayed at the POR last November we were suprised with 2 autographed photos one day. When we checked in both of my children came to the counter with us, my daughter said Hi and told the CM that she thought the resort was beautiful!(she's very outgoing). He then gave them coloring books and crayons to go sit at the little TV table with. After he checked us in he asked me who their favorite Disney characters were and I told him my daughter loves the Princesses and my son loves Pooh Bear and friends. He then asked me what their names were again and how to spell them, I had no clue what he was doing.
A few days later we came back to the room to find 2 autographed pictures, 1 from Snow White and 1 from Pooh Bear and friends, personally addressed to each of my kids. It was so cool and a really neat surprise. I'd never had anything like that happened before and it really was a magical moment for the kids.
Maybe after you check in you could ask the CM about it, I'm sure they could help you out.
Have a great trip!!!!!
