That's a good thing to do for sure. The problem is - my parents did that, and visited more than once, but every time they did, the teachers put up an act of being larger than life and the most enlightened experts of child development under the sun. Unfortunately, they believed them because the act was so good, and because years of life under communism taught them that going against institutions leads you to bad places.

I don't have the latter problem - I got the opposite problem from that, sometimes I hate the system a little bit too much - but still, remembering how the teachers used to threaten us if we don't put up our best act, meaning never speak out about the lies they told when other parents visited, I can't really trust few visits to give me an accurate impression.
