Dd now 17 but we've had this all through primary.
Her after school club up to 3rd class was attached to a crèche so they ran summer camp all day with themed weeks all summer. We tried to limit that to 2-3 weeks per summer so she didn't hate going there during term. But it was a godsend the summer my DGM died for an extra 2 days cover.
I would take some weeks doing mornings only as most "summer camps" were 10 until 2, or maybe 9 until 2 if we were lucky, DH could often have enough flex to drop her and I'd take the afternoon s off. Local sports and activity camps.
She usually did at least 1 week in the sports camp in the Uni based in city centre near my office that ran to 4:30 and had aftercare to 5:30.
And she also started, aged 6, doing sailing and the local sailing school runs all day camps all summer so she gradually increased to up to 4 weeks sailing in the summer.
And we'd also take our summer holidays of 2 weeks, and some years she would also spend a week with her DGPs who are 2.5hours away. And some years I took some parental leave or extra annual leave if we hadn't needed too much for illness earlier in the year.
Our holidays are 8 weeks long. And actually, summer was easier because of camps than Easter and Christmas.
