I did the same thing at my childhood camp. I was a camper, CIT, Junior, and Senior Councilor. This was before I moved on to be a director at a different camp.
First thing you need to remember is you are not a camper. So make sure to keep a professional distances from the campers. Especially no dating campers!(Setting yourself apart will earn you more respect than trying to be their best friend.)
It can be a bit hard as you will want to do some of the things campers get to do. Now you may be stuck in one part of the camp when in the past you could wonder and try out different things. So try not to not have any expectations of it being like it was as a camper. Come in with a open mind that it will be like a new camp experiences for you.
Honestly I loved being on staff more than I did being there as a camper. I got to help save camp traditions and bring in new ones. It was amazing being a staff member at the camp I loved.
