I had DS at the RUH 13 weeks ago 
I found the care of the midwives and health care assistants very good, both in the delivery suite and the antenatal /postnatal ward.
They only have one birthing pool, but If you let them know you want the pool when you call to say your on your way you'll more than likely get it, alternatively all the delivery rooms have a large corner both that you can ask to labour in, just requires a bit more help getting in and out!
They usually don't like you to plug anything in, the same room as the birthing pool has a cd/tape player radio thing which your welcome to use but I would take laptop and speakers and hope for a midwife who'll turn a blind eye to it!
They promote active birth and even tho I was on a ctg monitor for DS's heartbeat I was still up and wandering around, bouncing on a birthing ball that the midwife provided and up on all fours on the bed, only once I had to have an epidural because he was back to back did I have to lie flat / sit up to have him!
There is a good sized hospital shop that's open 9-6ish I think, sells drinks, snacks, newspapers sweets ect.
The food isn't bad, but you can always skip the lunch and go down to the hospital restaurant (and leave your baby with the midwives) also all of the local takeaways deliver to the postnatal ward!!
When you phone to say your on your way if ask if you need to pay for parking before you come into delivery, I was already in on the antenatal ward when I went in to labour so I'm not sure!
Hope this helps! If there's anything else I can answer I'll try
good luck!
