We did a lot of traveling during Passover with the kids. We had the opportunity to see wonderful sites, hang out with friends, and explore.
A couple years ago when we went to Disney World with our oldest three, I created phone number bracelets for the kids to wear. I have also bought the paper bracelets to write on. These are great for younger kids who might not be able to remember your phone number. Another tip I recently heard to tell your kids to find a mom or a police officer. Then have them ask the mom or police office to call you. The thought behind this was the mom with kids is most likely a safe adult.
