Yup, my birth centre had a 4hr discharge - that is the earliest they would let you go. With both boys I ended up staying in due to meconium - 2 nights for DS1 and 1 night for DS2 for them to be monitored, which I was completely happy with.

To be honest, I'd love to have stayed in longer with DS2, just to have the quiet time to get to know him, rest, have meals brought to me etc. Yes, I did miss DS1 during the 30 hours or so I was in there, but he was brought into visit me once. I am actually considering going private next time in order to get the longer hospital stay - but that's a story for another thread.
