Not sure the sunflower lanyard will help with queueing for rides but is useful for the airport.

The DAS system in Disney World sounds like it might be something useful but no one can really say they will definitely get it. They need to ask when in the park at Guest Services. Its a pretty straight forward thing to sort once there. You can't book in advance and its up to the CM whether they issue one or not but this is the type of thing they are meant to be for. If you go over to the Special Needs section you should be able to find some more info on this. They have a similar thing at Universal and Seaworld I believe too
