I've been in 3 different ones. Twice involuntary and once my choice. each hospital does vary but they're all pretty much the same. When I went voluntary I was put in the same place as everyone else. The only real difference was my attitude towards it. Also, even when ur voluntary u don't decide when to leave they do. And if u sign the paper asking to leave and they don't think ur ready they will change ur status to involuntary. Hope this helps if u want any more info let me know.
