HIIIIIIIIIIIGH MEADOWS!!! HIIIIIIIIGH MEADOWS!!!
(That's the school song, and yes I am their biggest fan.) Seriously, I could go on and on about the things we love about that school. The biggest problem may be that you'll never want your kid to go anywhere else and suddenly you're considering moving into a refigerator box so you can afford to send your kid there all the way up to 8th grade. And your kid, like mine, might not realize and aprreciate how good he's got it. ("But EVERY school has ponies, mom! That's not a big deal!" Grrrrr...)
Crabapple Montessori is also wonderful. (I have my younger son there, and he ADORES it.) There are a ton of Montessori schools around here, and some of them are a lot more... "faithful" to the original ideas of Maria Montessori. The Cross of Life one someone mentioned, also seems really nice, but as I recall, their hours are more limited, and it may be too far from Woodstock. The Crabapple Montessori, RIGHT behind the well-known Silos of Crabapple, is closer. (There's another Montessori just down the stret, on Elkins Rd - not nearly as nice, in my opinion.)
It sounds like the Village Montessori (I think it's on Roswell Rd. in Woodstock) might be the most convenient. That one looked good, too, but it was a little too far out of the way. It seems nice, but I don't know first hand. Any of those 3 would be a much better option than a Goddard or Creme de la Creme, mostly because the teachers have a teaching degree, and an accredited Montessori schools require special training beyond that. So you don't get the issues with constant teacher rollover that you do in Creme and Goddard. (It's the difference between daycare workers doing a job (some of whom may be excellent) and degreed teachers who view the job as thier career.
