Yeah I totally get camps etc that's an experience for kids, not talking about that but most people I know with kids it's at least weekly, but usually more frequent, activity, cinema, bowling, outing to Mcdonalds, trampoline park etc for the kids and their friends. Where I'm from summer holidays are 9-10 weeks as well but I guess it is different culture here with people working a lot more and not having family close by to help. Still though, surely it's possible to entertain kids without everything being a paid for exciting activity.
