We just returned from our first trip and the pen drove me crazy! We bought a "fat pen" from a gift shop, but kept losing it! It would be in my husband's pocket when I thought I had it, etc. Then I remembered that when my mom was working as a nurse she had pens with a string, to hang around her neck! I asked in a gift shop if they sold them and they didn't. Later I saw a little girl with one and my last hour in a park I saw a Mickey pen on a string in a gift shop. It may be a hazard, get caught on a ride, so I wouldn't put it on the child, but if you wore it you could find it!!
