It becomes a tradition, starting with the Fab Five, for the mentors in the Justice League to send their sidekicks away to summer camp for a month every year, from the ages of 12-16. When asked, the parents say it's so the kids can have a vacation and just be kids for a bit.... But it's also so they can have a break from having heart attacks from their snarky hardheaded teenagers throwing themselves into danger. Just for a little while.
They know better than to send the kids to separate camps (sending them away is hard enough to sell them on, sending them away without their friends would go over about as well as wrestling a pack of rabid coyotes, these children are a package deal, do not separate) and the camp has been vetted very thoroughly by both Bruce and Clark.... And because the parents are all paranoid (for good reason), J'onn goes undercover as a camp counselor to make sure they stay safe and have access to the league if they really need it.
The only ones who never complain about being sent are Billy (Who Bruce insists should go and foots the bill) and, later, Bart and then Jon. Not because they don't have a good time but because each year they all take themselves a little bit more too seriously, and summer camp is a great way to remind them to chill out and be kids while they can.
(Jason only complains because he always gets homesick and misses Bruce and Alfred, not that he's really willing to admit it.)
(Damian only complains the first time.... And then promptly becomes a Disney Princess among the forest critters when he gets there. It's getting him to leave that becomes the problem.)
Wally and Roy "accidentally" make flamethrowers out of their bug spray one year and nearly get sent home early. Kon takes up soap making/carving, Donna likes flower pressing. Dick is the best at giant Jenga. Steph and Cassie steal Tim, Bart, and Kon's clothes and hide them around camp. The boys get their revenge when they play paintball. Tim is having the time of his life taking photos of all his friends smiling so much. Jon enjoys the scavenger hunts and has never seen Damian this happy (while he feeds an entire family of raccoons).
They all have more friendship bracelets than they know what to do with.
Heroism can wait kids, go climb on some rocks and toasts some marshmallows, build some stuff. Your moms and dads are gonna keep the letters you send them forever and give you the biggest hugs when you come home, promise.
