200 right now for us...we're a family of 4. Its a nice start! LOL We will be needing more, as we'd like to share our points a bit more and find we really don't have enough to do that. Also we're expecting child #3 next spring....so in a few years we'll need bigger rooms.
Ideally, we'd like to add another 200 points or so...300 if we can ever manage it. Right now we just have other priorities.
