Space Center Summer Camp (ages 11-14) reviews?

My son is extremely into nasa and engineering. We couldn't get into the space camp in Florida and in my research, I saw the Johnson Space Center also has a camp. I was wondering if anyone had reviews of the camps there for 11-14 year olds? It's a couple hundred dollars more, so I want to make sure it is worth it before I delve into it more.

Thanks!
