My daughter is a young teen (14) who has ADHD. She seems fine most of the time. We are going to WDW in after school lets out in June. We have always gone in January before when it is cooler and lines are shorter. We also used to go with my mother who rented an ECV (she passed away this year). If my daughter doesn't take her meds, I fear how the extremely long waits and heat will affect her by mid-day, since she becomes prone to tantrums when frustrated. If that happens, I "lose" her for the day. If she does take her meds and wear her patch, she gets nauseous and loses her appetite and I won't get her to eat or drink much-needed water to keep her from dehidrating. I've been reading about GAC's and I don't know if her issues qualify. More importantly, I can't tell from reading the posts what help a GAC might actually provide if she does qualify. She might be embarassed by going to Guest Relations to discuss the matter and I don't want to put her through it if the GAC won't make much of a difference in her ability to enjoy the experience anyway. Can people share how the GAC helps at specific rides? Haunted Mansion? Soaring? Space Mountain? Splash Mountain? Aerosmith? TSM? etc? I just want to get some thouhts to decide if I should try to get one or just hope for the best without it? Like others who have posted here, I'll use fastasses whenever possible intead. Thank you.
