Apparently, or at least so I've read, you can bring pillowcases to customer service and the characters will sign them!!!
Here's some hints that i've read -
1. It has to be either a plain or disney pillow case, no star wars or barney, etc.
2. put it in a ziploc bag with a sharpie marker (waterproof and indelible ink) and label it with your name and cabin number,
3. pick it up a couple of days later
Sounds like a pretty cheap souvenier for family and friends back home to me (I"ve currently got three in my packing pile).
Hope this helps,

see you in 14 more sleeps!!!!!
