I was going to say, as far as I knew if you had a previous csect they didn't allow you in birthing center's. As for the 24 hr thing most birth centers I have heard of have a strict 24 hour policy and if you feel the need to stay longer they have to transfer you to the ward. But you could be lucky, I would advise ringing around and finding out what their policy is.

Goodluck, I would love to hear what you find out!
