Last year when we went to WDW, we got a DAS for my daughter who has a congenital heart defect. She has a hard time regulating her body temperature and heat/sun seem to wear on her more than most kids. We wanted her to be able to wait out of the sun and heat for rides with long waits. We also had stroller as a wheelchair so that we could have her stay in her stroller sometimes for stamina reason and to give her a safe place to be out of the sun and crowds. This year she was diagnosed with sensory processing disorder and we will again request stroller as a wheelchair so that she has some place to go when she is overstimulated. This has worked well at home. My questions is, I saved the DAS from last trip, can I take it to Guest Relations and have them scan the barcode to pull her up in their system? Will I need to explain again what accommodations she needs (I realize I will need to do this for stroller as a wheelchair)? I just want to be prepared. Thanks for the help!
