Yes, they do tours.
Call the salesman over the area your company is in. Be honest, tell them you aren't in the market for a new plane but are in the area and would like a tour.
We got a full wine/dine experience for our tour...4 course lunch, goodie bags full of Nike merchandise, G150 demo flight...even with me telling the salesman multiple times "we just got a Citation, we're not gonna be getting a Gulfstream, even a 150, for a while."
He told me "any jet owner is a potential future Gulfstream owner".
VERY nice digs there in SAV.
