I'm 32 weeks today and booked at Georges. Took ages to get my booking appt (GP had my +ve result at 14 weeks, booking 22 weeks), but apparently my GP should have faxed the paperwork and told me to phone for an appt, not to wait for the process.
Still, apart from that the midwives have all been lovely (phoned once very worried, couple other routing queries, 3 visits), and I've previously seen the head consultant obgyn, who is excellent and a really nice guy.
I've also gone on the tour of the delivery suite and midwife-led unit, both looked impressive although the MLU is triage only, you can't book it, so may not get in there even if low risk. I think Tommies you can book but still may not get in.
When I needed a referral for SPD, I was offered a same-day midwife appt (I went next-day), had a physio appt in 3 days for the next week, and the obstetric physio was fantastic. They did lose my blood test results but got someone round so I didn't need to queue again. The scans were great, both dating and late anomaly - took the time to explain lots of stuff.
Like Tommies, it's a huge busy teaching hospital and tertiary referral centre (so deals with lots of high-risk pregnancies which affect its caesarian rates etc). Obviously I don't know what it'll be like actually giving birth there but I figure it should be OK with MrNC and two friends to be there and demand food/help/care as necessary.
My NCT class is split between Georges and Tommies and the tutor says they're pretty similar. The MLU at Tommies has a lovely view over Parliament but you won't appreciate it at the time!
