Here are some of the pins I started with that I bought through Ebay.
I take all the character pins along so I can help entertain children while we are in lines or waiting for a show/parade to start. I get out a pin and ask who it is and start a conversation with the child/children. I think I've saved several parents sanity and mine with this entertaining method. I even got a child to sing me a disney song.
That helps offset the children who are just rude and inconsiderate along with the parents of such children. During Fantasmic, I had a child behind me literally put his hands on my shoulders and lean on my head. The child beside me was the cousin and she literally kicked my hand with her feet during the show. She got a very strong teacher glare that stopped her from kicking again. I liked the parent in front of us that told her child, "If you stand on the bench, we will leave the show." The child sat and watched. Or the child that pushed me and the parent made them apologize and then say, "Excuse me can I get by?" In such a crowded, exciting world, it is good to know some parents use the environment to teach manners. Others do not.
