Cherina,
Dont worry about POW hospital, you will be in great hands. I was once registered at St TEresa's (private)and put down HK$6000 no refundable deposit. I ended up at POW after weighing up all the costs and benefits. The major turning point for me was that i heard and know for a fact that most private hosiptals do not allow for the baby to be next to you at all times, I felt that this was not good especially if i wanted to breast feed on demand. Having the baby next to me made me feel much for secure.
During my consultations with a few doctors outside, they all had admitted that POW was a v. good choice.
Do not expect 5 star hotel service with the smile courtesy and politeness of 5 star hotels, for that you will need to check into a hotel. For $100, I can live without anyone smiling at me, it's a hospital, i just need to check in with professionals handling my birth and check out without much complications!
In all fairness the delivery team were very professional, and tried as much as possible to attend to my needs. Do note that they do have a group of teaching staff after all it's a teaching hospital. Contrary to talk outside, they are all supervised by Experienced doctors and certainly will not handle you object
My baby is now 8 months, I would definitely go back if I have a second baby.
