I asked this on a forum (can't remember if it was this one or another) as I am in the same boat re: driving, and was told that there are two condos nearby - Heritage View and Dover Parkview, that are possibly walkable. HV, apparently, might have a back gate to make it even quicker.
However apparently the main concerns about walking are the humidity - it really does get uncomfortable, so I've been told. I had a theory in my head that a morning trot to school wouldn't be a problem as we've been to SE Asia lots of times and cope with the heat quite well, but it's the stickiness that's the problem - and I have to remember that these were all holidays, and if I'm rushing along to school with a small boy hanging off my arm it might all get a bit, well, sweaty...
So the school bus is the other option, and there are lots of threads about this (do a search using top right-hand box) - I'm apprehensive about this simply because we've never done it before, but I am also told that it's a key point of the day for the smalls, where friendships are formed and a lot of the social stuff goes on. Not to mention making life easy for us.
I've got a provisional place on the bus for him and hope to make a go of it. School bus journey will also, apparently, dictate where we live since the closest condos do not necessarily make the shortest time on the bus. This is all to come, once husband gets out there (June) and starts making proper arrangements - but the condo we choose will definitely tie in with the bus route, I think.
Of course I'm only spouting what others have said, being still in the UK, and all of this has been gleaned from obsessive combing of forums; am by no means a horse with a big mouth

Anyway now I'm rambling; see you out there.
