Ahh yes, DB vs CWB/SK.... typed out long reply which got 'timed out' so will try again, apologies for note format....
Agree with everything MuffinTumMum says about DB & HK. DB offers a great family lifestyle, well organised, efficient etc, but it is a purpose built 'town' and some call DB 'Milton Keynes by the sea'. Also, some would say it lacks Hong Kong character, but I can't knock it for a fantastic family lifestyle.
For us, it is SK over DB any day!!! To be honest, there is little to choose between facilities, classes for kids, meeting people, making friends etc. We have great beaches (cleanest water in HK), islands, hiking, swimming pools, water sports, tennis courts, athletics track, yatch clubs, schools, bars/restaurants/cafes, bookshops, food shopping, all the classes here for kids, art, dance, pottery, sport etc.
SK was once a traditional Chinese fishing village and the local heritage and culture remain strong. Life in SK is laid back, without the pace of HK island but with heaps of charm and the best bits of Chinese culture. For me, that's the main point of difference between SK and DB.
I'm going to post this now, but will carry on in another message.
