I'm in the same quandry - sort of! I really want to go to Wallingford - I'm five minutes' drive away - and if I manage to go into labour normally between 38-42 weeks and my baby isn't deemed too large, that's what I'll do! But I may need to go to the JR if I'm given compelling evidence that my large baby is too large. Not nearly as keen!
Have you been on a tour of the St George's Unit at Wford yet? I think they're on monday evenings and saturday mornings: ring 01491 826037 to book, and you need to ring about half an hour beforehand in case they have someone in labour! It's a great unit, laid-back as people have said, and chances are you'll be familiar with the MWs on duty when you go in. Two delivery rooms but apparently they have never had to turn anyone away yet. One pool, smaller than the one at the JR apparently (one?? I had no idea there was only one in Oxford!!), but large enough. Balls, mats, spanking new birthing stool, stereo and dimmer lights in the delivery rooms so you can get all atmospheric... Post-natal ward looked lovely and homely, four beds, and a living room and kitchen for your use. Has a relatively rare UNICEF rating for excellence in breastfeeding. Heaven, basically! God, I hope I can go there... And no, there are no immediate threats to close it down, apparently, despite it being on 'the list' for ten years.
Sadly, they have now stopped tours of the JR wards due to staffing (how many people does it take??) and the heralded 'virtual tour' that they promised they'd put up on the net is nowhere to be seen. I rang and asked and was told it's unlikely to be up before my due date of march 2nd. However, the JR is a national centre of excellence (for non-normal births) and reports from various friends have all been positive. The idea would be to transfer to Wallingford for a night asap, though. And I was advised by a Wford MW to ring them about this from the JR, rather than rely on someone at the JR to sort it out - they might try to tell you it can't be done.
Sorry, too verbose! I really hope you get to go somewhere you feel relaxed and happy - and good luck!
