I remember getting lost when I was a kid at FW. We got off the boat from MK and in the crowd I lost my parents. I walked for a minute or two before I realized it and then did what mom and dad told me to do over and over again...STAY PUT, sit down right where you are and don't move even if an adult asks you to, tell them you are lost and that your parents are looking for you, and tell them they can wait with you. Worked for both me and brother, and he got lost much more often than I did
