My dd is going to Busch Gardens with a friend. (No parent will be along) How should she carry her D stuff? She doesn't need much -- just her insulin pen and testing stuff and some carbs. Should she carry a backpack? But then she'd have to check it in all the time. Can she stick the stuff in a waistpack? Are they allowed on rides? Any other thoughts are welcome -- I'm not familiar with the rules, and the website for VG isn't particularly helpful!
