Had 2 vehicles to get NV plates and registration for. Went there at 10:30am and was walking out the door at 11:15. I was amazed. The place was packed. A couple tips:
1)Make sure all your paperwork is with you
2)Yes, you must wait in the long line in order to get a number.
The service was friendly, enough, and the place is huge.
No painted lnes on the floor like in CA.
