I use to live in Ft. Lauderdale, well in the Weston area. It is very nice, but it is predominantly spanish/portuguese speaking population. Your child or kids will go to some pretty good schools down there, but I strongly suggest you talk to them about drug use, there is a lot of that. If I had kids and decided to move to Florida, I personally move to the Del Ray Beach area (about a 1/2 hr north of Ft. Lauderdale) Or West Palm Beach Area. It is much nicer, cleaner, and safer. I know that some people are not as comfortable moving into an area where English is not widely spoken. I wasn't comfortable at first, I use to feel like they talked about me when they knew that I couldn't speak spanish. I did not dress like them either. Fashion is big down there.
There is a mall down there Sawgrass Mills. We use to go there all the time. Some of my friends told me that its bigger now. That is an awesome place to go! It is either located in Davie or Sunrise (in the Ft. Lauderdale area). Ft. Lauderdale is big! you have down-town Ft. Lauderdale, Davie, Sunrise, Shenandoah, Weston and Weston Hills. The best place to live would be Weston Hills.
Hope this helps.
