I also gave delivery in Queen Mary. My husband just parked the car in Aberdeen. you drive the car along the main road .... pass " cookery school" .... pass " tsz fu garden" then after yu XX secondary school. The carpark is opposite to this school. Only $5 per hour. Because the carpark is on your left, so, you have to drive to the fire station and U-turn, then back to carpark. Very convenient. So, sorry that I don't know how to type "Chinese" Remember go straight along the main road. Pay attention on your left... about 5 mins to go.
After parking your car, you should take a bus or taxi ($15 ) go to hospital. It's cheaper than Queen Mary
