Parents, how do you manage summer breaks, who takes care of your children when there is no school?

On the one hand, I'm lucky that my wife works at a daycare that runs day camps for children up to 8 (my daughter is 5), but we still don't like that she spends the entire summer with strict schedules and things like that, so that for 15 days she goes with my in-laws and 15 with my parents, in both cases they are retirees in very good physical health and eager to play with their grandchildren.
