It sounds like it would be a good outcome either way. I've read about Peter Lucas and it's good to read positive stuff about Jan, as I was going to contact her when it's our time again. Do you feel comfortable with Peter? Is there a cost difference?
It may also help your family etc if you tell them you'll be having a doctor and a midwife. (Not wanting to disrespect midwives, who are more than capable, of course).

GL - looking forward to hearing how it all goes.
