Doral is west of South Beach and Downtown Miami.
The Doral area is by MIA International airport so you have a lot of corporate businesses and warehouses around there because of the proximity to the airport.
It all depends on the lifestyle you and your family would like to live because there are many different sections of south florida that offer a kind of lifestyle for very different people, cultures, and incomes.
BEFORE YOU COMMIT TO A HOME....you need to consider the drive and traffic.
Living in Doral you'll be 45 mins away from everything in Miami basically. But getting to and from work in rush hour traffic can turn your drive to work or home to 1.5 hr. minimum.
For example, if you want to live by the beach...You would have to live basically across town from Doral by the water and enjoy more of the popular Miami lifestyle
Since you have young kids you'll probably be looking more for them.
Doral is located in Miami-Dade County and just north of Miami-Dade County is Broward County.
Here you will find more of an upscale family lifestyle with newer home developments and houses/townhouses.
Doral has a famous golf course that host a huge professional golf event and is hosted by/owned by Donald Trump. And there a couple other golf courses that surround that course, so the houses that are on or by the golf courses are nice.
Not from that part of Miami...I am more on the east side on the beaches.
If I was in your position I probably would look at Miami Shores. Lots of families and children. Diverse group of cultures. The drive to and from work during rush hours is not going to be good, but this is Miami and its like that everywhere.
