Natural birth in hospital setting?! Advice!

Hi all!
I'm 27 weeks with my second pregnancy. Im going to have my baby in a traditional hospital setting however I REALLY want to go the natural route (no epidural, no pitocin, etc.). I've heard, however, it's somewhat challenging to try to have a natural birth in a traditional hospital setting, like the nurses and stuff may try to push certain policies such as no walking around, having to stay on monitors, etc. Anybody been in a similar situation and can provide some advice?? Thanks so much!!
