Ban Chang, Rayong is handy for schools, also easy access to Motorway 7, Au Tapau airport next door, quite a lot of reasonable priced housing, 3 main beaches, a bit more open spaced than most places, great infrastructure now, half way between Rayong city and Pattaya. The air also quite decent here with the wind coming off the beaches. You need to have a look around, start with Google maps and see the layout of Rayong province.
