I have DD14 and DS 17 who plan to take off on their own in the parks. This is our first trip. I am under the assumption that they will have a card to carry around all day to get in and get fast passes and DDP lunch. Am I correct? Is there a hole in this card to hook it onto a lanyard or is there some kind of around the neck holder that will work? I really don't want them to lose their cards. Thanks for the help.
