play yards or roam free?

Shannon
My son is pretty much crawling now and I'm not sure where to put him so he can roam.
Are you guys just baby proofing everything so they can freely roam the house/a room or does anyone have a play yard?
I was thinking about getting a play yard so my son has room but is confined. We have wood and tile floors and two cats so I figured I could pad that area and keep it free of pet hair better than my floors ha.
Thoughts?
