One of the things I want people to know is when it is appropriate to call an ambulance and when it isn't.
I don't want them calling an ambulance for every seizure but there are certain times when it should be done.
Making sure all the staff, from the ones who have been there a while to the newbies, is a good idea.
As to the guests overhearing, I once did a short presentation on epilepsy during a huddle and a guest was walking by.
She came up to me afterwards, showing me her medical alert tag, and was effusive in her thanks for sharing the information.
She was older and had grown up when you hid that kind of thing.
