Visitor, I just read your other posts and realised that you're not actually pregnant yet. Instead of spending HK$16,000+ on QMH, spend it on some good maternity medical insurance. If you sign up for a UK insurance company's plan now (Allianz, BUPA International, Morgan Price...) then sign up with Dr. Philip Ho you will have to pay him HK$5,000 when you join but will not have to pay any more to him (or a private hospital) until you're 36 weeks at which point the insurance co's 10 month waiting period would be over and they'll get to pay the rest!!!!! I've had a broker look into cover for me, and the prices for someone 26 - 30 start at GBP65 per month.
I had my baby at QMH last year and really hated it so if you can avoid it do!!!
