Hi Ida,
Brunei Darussalam is a small and really peaceful country.
I notice that you are coming with your family and it is really the perfect place for family life with yound children.
For Education , the system here is quit good and you will be able to find good quality government or private school for a reasonnable price.
For shopping , according the size of the country and the population (around 400000) , it is not so bad . In Bandar Seri Begawan, you will find some good shopping mall and mostly shopping areas . The MALL in Gadond and Kiulap shopping area (the amount of shop is really huge). For nice designer boutique the choice is limited.
We are here for one year now and really we have no regrets at all.
