T.,
My sister Michelle was there this past weekend (Thursday - Saturday) and she went in at about 1AM. I headed over there at 2:30 to be with her (I live really close). Anyway, they told her that she may have a roommate after her son was born. She was worried about it. As it turns out, from the time I got there until she went into actually pushing, I saw FIVE Mom's come in that were in labor. I thought for sure she was going to have to share.
Then, while at the Cafe by the main entrance, we saw 6 or 7 leave. It was a crazy busy time for them. Michelle never had to share a room. :)
Good luck and enjoy Good Shepherd. I delivered both of my sons there in 2005 and 2007 and the staff is absolutely amazing. They are so attentive and encouraging.
