Visiting CGR International in Madhapur about class 8 next year, without my son

We're starting early. My son is 12, starting class 7 in June, and we're thinking about a change for class 8. CGR International in Madhapur is on our list, and I've managed to get a visit next week. Vaadu has refused to come. Says if he sees it he'll 'have an opinion' and then we'll argue. Fair, I suppose 🙂 So it's just me and my partner. For parents who know the middle classes there, or anyone who has visited for class 7 or 8: what should I ask about, and what should I try to see, so I can describe it properly to a boy who doesn't want to hear about it?
