Definitely agree with all of the above. I was in the exact same position as you last year, tossing up over C&S and BGS. Loved both schools although DD was slightly biased towards one. Honestly if you can't split them, choose the closest one. I was still stressing whether we had chosen the right school after submitting the CAF form but so relieved a few weeks down the track when it was dark at 4.00pm, that we had picked the closer of the 2 schools. A year down the track I know we made the right decision. I think DD is coping so well and enjoying many after school actiivites because her travel time is minimal - I really think she would have been happy in either school but we are glad we made the choice that gives us all a better quality of life. I also like the fact that I can pop out and pick her up when necessary if she has activities that finish late, in minimal time. Of course many children travel quite a distance to school each morning - some have no choice and some travel to schools that are better suited to them but if you like both schools then why not make life easier for yourself and your DD!
Good luck with your decision - either way it won't be a bad choice
