I ran into a situation at the Air & Space Museum at Dulles. I had my D800 and 24-70 F2.8. No tripods or monopods are allowed, lighting is very poor, subjects are large and long (aircraft), many are very dark (SR-71), no room to get reasonable distance, secondary lighting not possible and second floor moves with people walking. You need good DOF which limits aperture, and fast shutter but lighting is poor. Very high ISO will show up on dark subjects, ended up will very slow shutter speeds. This is where VR would have been beneficial for me. I did get a few good shots, but feel that VR would have improved keeper ratio. That darn D800 shows up every artifact of my poor skills!!
The pros can get special permission to shot with tripods and additional lighting during off hours, not so for us "plane" folks (pun intended)!!
Anyway, I have since got ahold of the 16-35 VR and when I return to the museum hopefully will have better results.
