All right, assuming that you don't have fond memories associated with the SUYA like all of us OCS grads do, there are a couple of nice things about Pensacola. The museum is a great idea. Everyone likes that. Be sure to catch a show at the IMAX while you're there. Just not the fighter one. "It's gay" Not my words, those were spoken by a fighter pilot in reference to the IMAX show. I think it's about Red Flag or something like that. The helicopter one is all right.
As for the Blues, assuming they're not on tour (which they very well may be in the middle of the summer) they practice on Tuesday mornings. You can see them from pretty much anywhere in the city, though the museum parking lot would be pretty prime for viewing that.
Other than that, from an aviator wannabe point of view, you should stop by "Wings" aviation supplies. They've got some pretty good stuff there. Go there before you spend more at the museum gift shop for the same thing. Ask where it is. You really can't miss it since it has an F-4U Corsair on top of the building.
Otherwise, unless somebody in your group is military and can sponsor you on the bases, there's not a whole lot else aviation related. Don't worry, though. There's a whole lot of other things to keep you happy.
