We started preparing everyone months out by saying how much we were looking forward to the first day just being the three of us. Add to the end of the BA text/FB update (which can go out a few hours afterwards) "No visitors until Thurs. Please phone beforehand". We did that so we didn't end up with lots of visitors at once and so no-one turned up outside visiting hours. Don't be afraid to let people know you're tired or just not up for visitors. The sign on the door is a last resort - if you'd told people, texted and they still turned up, they'd have to be pretty darn thick, lol!!!
