so what happens if you fly to WDW and somehow lose your ID during your trip? What happens when you go to fly home? I always worry about this kind of stuff. DH has two licenses so he always keeps his spare in his luggage but I don't. And what about my 4 year old? What will they ask for her ID wise at the airport? We fly northwest. Do I need anything? I do have a little kid ID card and one that I wrote on that she got for her class picture...they spelled her name wrong on her ID card so would that be an issue?
