Well, I did visit ITER back in 2014, it was really nice, we went on a tour, saw the facilities, attended a presentation, saw models of the reactors, etc. It was all for free (but the train ticket). We were a small (6) group of students who asked if a visit would be possible, and we were pleasantly surprised by the answer. There was at least one other family with us, so it's not just students.

Making money isn't really the goal for ITER, though. PR and education is. The tour left us with a pleasant feeling about ITER, but we weren't the ones to convince. I didn't see that kind of tour advertised in any brochure.
