I know one of the senior midwives at dr greys and just from speaking to her I don't think she would come under the "old fashioned" banner. She is quite forward thinking actually. The unit might be a bit dated, but if you maybe give the unit a call you can maybe have a visit to see what's what. They have to respect your wishes and if the pool is available and there are no other risks you should get to use it.
I was pg at the same time as a friend from Elgin, and so we regularly swapped notes about our pregnancies. She opted to go to Aberdeen in the end, rather than giving birth at Dr. Gray's. There was no epidural on offer there, and she found her consultant and some of the antenatal midwives to be very patronising and bossy. The ethos sounds a bit weird, but maybe that was just my friend's experience, I don't know.
