jane01... i lived in db for over 6 years, much of that time without kids! i miss it terribly! we were there last sunday, and now, i miss it even more!
there are downsides to it: ummmmm.....let me think... i'm sure i can come up with one......ah, yes! you have to travel to tung chung for a cinema!
no wet market, but there is a wet market in tung chung if that is what you are after. when we first moved to db, there WAS chinese-y type market that had fresh fish, veg etc. kind of like a small wet market, but it closed shortly after we moved to db.
also, regarding transportation. we never had an emergency where we had to be "off the island" immediately. that includes two terrible pregnancies with lots of hospitalisations.
just wanted to say for the record, i LOVED having the ferry ride when i was working! after commuting to work via mtr, taxi or bus for 6 years prior to db, both hubby and i LOOKED FORWARD to the ferry! it is comfortable (although a little cold at times), convenient, generally quiet in the morning (people reading their paper, sleeping, eating breakfast, working on their laptop) and in the evening there is almost always someone you know that you can have a chat with, enjoy a beer etc on your way home. it was "wind down" time built right into your day!
the ONLY time it was ever inconvenient, was very late at night/early in the morning (12-5am).
