K.P.
Both of our kids have always shared a room. We have a boy 6 and a girl 4, and they are great friends. We have never had a huge problem with them playing when they are supposed to be sleeping, but they do get the giggles sometimes. We are in the room right next door, so all we have to say is, "go to sleep," and they get quiet. We don't really mind if they whisper to each other for a few minutes before they fall asleep. It's actually funny to listen to the conversations they have. We decided to add a basement so that they will have their own rooms. It isn't quite done yet,(husband is doing all the finish work) but we know that even if it was, they are not ready to be down there alone. Being that they are opposite genders they will eventually be separated, but no need to yet. I think sharing a room is a great thing for young kids. They learn to help each other clean the room because it isn't just one or the others(teamwork). I think it helps in keeping our family close knit for now because we don't all retreat to different areas of the house. Our kids spend a lot of time playing together, reading together, and just being kids together. As they get older I know this will change a bit, but as freaked out as I was as the idea of our kids sharing a room, I am so glad they do.
