One point I would just add about telling someone in a CH that they're staying there: if the person can't accept that there's anything wrong with them (as so often, no matter how bad they are) then they are never going to accept that they need to be there, and not at home.
And when I say 'can't' I mean that literally. When someone can't remember that they can't manage at home any more, maybe can't even make themselves a cup of tea, then it's no wonder that they can't be happy that they've been taken from home and put in this place. Imagine being convinced that there is nothing wrong with you, and yet you have been put in this place where you don't want to be - it must be awful.
Hence, IMO, the LWLs are the kindest option. However, as always, every person is different and each of us who knows them best will usually know better than a professional who doesn't really know them, what is best to tell them.
