I agree with Elizabeth about College Park. If you were to move there you would have to do private school for your kids. North Fulton County would have pretty good schools, which would be Roswell/Alpharetta area, as would the East Cobb and south Cherokee schools. It is just a bit further then Alpharetta, but I think it would be worth it for the schools, would be south Forsyth county. I am a teacher and I have to say that school system completely impressed me when I was interviewing for a job. It is probably 45-60 minutes to the airport, depending on how close to GA 400 you are located.
I would steer away from south of the city. Henry County is one of the fastest growing in the state, but the schools are quickly becoming overcrowded. I would stay close to GA 400, Fulton, Forsyth, Cobb or Cherokee Counties. Dunwoody is another popular area, but I don't care for the school system (Dekalb County), although there are some great Elementary Schools in there. Hope this helps and good luck with your move.
