Hypnobirth

Sanel
So from the day I found out I'm having monkey I've wanted a water birth with relaxing music etc in the back round at a birthing centre. Only problem now is some issues have arised an I may have to be in the labour ward an only luck will tell if I have a pool.  
My question is do I push for a water birth like originally planned or do I stick to gas an air and a bed ? Have you had both how would they compare, have you done one what would you say would you change ? Ta :)
