Playroom vs Bedroom

If at all possible, I believe in having a playroom rather than kids playing primarily in their bedrooms. It keeps their bedrooms cleaner and keeps distractions down when children need to go to sleep. We don't have any rules against our boys playing in their bedroom, and occasionally they will go play with toys in their room in the middle of the day, but they tend to gravitate toward the playroom and we have never had any real sleep problems with any of them.
