I have a question based on an idea my friend and I had regarding meeting characters on our upcoming trip to Disneyland this August. We thought it might be cool to have the Disney Characters sign store bought t-shirts rather than in an autograph book (figured getting them to sign a tee was "cooler" for us big kids ). Do they do this or have any problems doing this?

We plan to visit a couple character dining places such as Goofy's Kitchen and the Plaza Inn for Breakfast, as well as maybe hit-up a few meet and greet spots at the Disneyland Resort theme parks themselves. I just want to be sure that if we hand a character a t-shirt and a sharpie marking pen that they will go ahead with signing it and we won't be stopped by their handlers.

Thanks for any help!
