Thanks for all the responses. As mentioned, it didn't occur to me last year to tip. But when we did give out gift to the swim instructor, a college student, she was pleased. It was only $40 but every dollar counts when in college. So I feel OK about this.

With teachers, I think that can be a different story, since if a Christmas gift, the student would still be in the class after the gift. With my story, it was the end of the session and strictly appreciation.

Strange that no one had a similar experience with camp. I thought there would be one.
