AaronB,
I recently relocated to HK with my husband and 2 small children - 3 years old, and 9 months old. I also heard great things about DB and maybe it was the hype but when I went to visit and toured 20 apartments and even visited a friend-of-a-friend who lives there in an amazing flat, I found I didn't like it. Perhaps my expectations were too high due to all the great things I heard?
We spent time in the plaza and the pollution from the buses and the ferry, combined with the cigarette smoke- was just too stinky! Also, even though we have children, even we were annoyed with all the dogs and kids running around!
I think that it is true it may be easy to meet people in DB, especially if you are expecting your 1st one and for a first-time mom it is always nice to build that support group soon after moving to a new country. It really is just going to depend on what you are looking for in your place of residence. DB seems very contained, which is not what I wanted.
Just my two cents. Good luck with your search!
