It is interesting to note that the Chabad overnight camps only take the best bochrim from the yeshivos with multiple references to be counselors and learning teachers in their overnight camp.
I was once visiting Gan Yisrael Montreal, and stayed late. Late at night after lights out, and an exhausting day I saw many counselors sitting and learning in the Beis Hamedrash.
The result is that the children come back to yeshiva and cheder with new chayus in learning, davening and mitzvos.
We can learn from everyone, even Chabad.
