DS7 attended the SIG 3 week day camp earlier this summer. He wants to attend next summer. He did "game theory" where he learned chess strategies and other strategy games, an earth sciences class, and a chemistry class. He loved them all, but his favorite was the chess...that teacher was particularly enthusiastic. His most challenging part of the camp was coming up with his own project. He is so used to school telling him what to do and study, that the novelty of that threw him for a loop. But he chose tornados for earth science and had fun.

Disclaimer: my son is 2e (autism) so for him, fun is staying busy and not being bored by lectures. He had to use his "strategies" of leaving the room a few times to avoid being disruptive during "boring times" and the teachers were tolerant of that. Also, the play periods were hard for him (like a lot of unstructured things are) especially because there were older kids who wanted to hang out with themselves, and not a 7 year old little boy. He wanted to do things with a group of older (9 or 10 year old) girls and they (of course!) wanted nothing to do with him.

You are right about the cost, but for us it was worth it. It was a great transition from school to summer. I can answer anything else in more detail if you want. nan
