My dd is three and is quite the wanderer, so this is something that I have been thinking a lot about. I am going to fold over a note card (so no one wandering around can see the information) and put her name, our names, our hotel and room number, and cellphone number as well as what walkie talkie channel we will be communicating on, laminate it and safety pin it to the back of her t-shirt. I will also be sure to have a photograph taken within days of our leaving with me to help CM's locate her quickly...how many 3 foot tall blondes wearing a pooh t-shirt do you think there are at MK on a given day???
Hopefully, that will return her to us very quickly. More than that, hopefully, we don't have to test the system!
