are baptist rooms shared?

the post below got me thinking...

are the baptist rooms shared?  when i delivered at jackson, they put me in a private room, i didn't ask for one, and turns out that they have shared rooms, too.  However, my insurance refused to cover a private room for me (even though i had no other option) and they've been charging me close to $1000 bucks (but i'm not sure if it was for abby's birth or the week i was in the hospital the week before.)
