A "dream dive" (as in..."in your dreams, buster!") would be the zero G trainer at the Johnson Space Center in Houston. Bad part is not having the proper security clearance. I remarked to a couple of their divers that I'd give my eyeteeth to dive there. One remarked, "Well, we'd let you, but then we'd have to kill ya'."
I said, "What are y'all hiding, a Russian spy satellite?"
The one who spoke first looked at his partner and replied without batting an eye, "Looks like we're gonna have to kill him anyway."
But it would be a great dive!
Along those lines, there is a 60' tank at the Pickle Research Center in Austin. They do a lot of sonar research there.
