I have flown corporate into TAC Air for almost 20 years now. It is just across the parking lot to get to The Perfect Landing. Tell Dan Bryant the FBO manager that I sent you.
Denver Jet Center or TAC Air are both good FBOs. Either one can square you away with a rental car. I believe DJC has an arrangement with Enterprise and TAC is with Hertz, if that's a consideration for you. Between the two, TAC Air usually has cheaper avgas... both are adjacent to Perfect Landing restaurant.
