I have worked at a few different types of camps.

My "home" camp is a 7 weeks of one week sessions. The great thing about it is that each session is different. Any given week there can be multiple sessions going on. We have pretty much everything - elementary, jr. high, sr. high, special needs, music, fishing, and a whole bunch more. So counselors never really get bored! The camp does a really great job of keeping consistency session to session, while keeping things new and exciting.

I have also worked at a camp that was a 3 or 6 week session. It was great getting to know the kids so well, but I will admit it got boring being use to doing so many different things. (I was activity specialist - so I was just doing my activity over and over)
