International Schools - Chiang Mai

Yesterday I took the day off work to go around and look at all the various International Schools here in CM and speak to the teachers/admissions officers: APIS, CMIS, NIST, Grace, Lanna. Two that I haven't checked out yet are Varee and PTIS (although I'm quite familiar with the latter owing to past experiences).

I'm not sure if there are any current posters on here who have kids in school here(?) but if anyone has any experience with any of them (good or bad) in any capacity (teacher/friends etc.) I'd be interested in hearing any opinions or feedback that you might have.
