Hello,
Yes, we would send our children to a nudist summer camp so long as we checked it out first and met the counselors.
Just as with everything else, if you know the people running the organization and see how they interact with the children and teens, you can pretty much make a decision as to whether or not you and more importantly, your children will fare in that location.
There are plenty of bad things that happen to kids at regular camp and we don't talk about shutting them down.
Let good judgement be the guide and you almost can't go wrong.
