Love love love the new option of making an appointment. Yes!!! Of course, unless you are quick, the appointment most likely won't be until the next business day.
There is a separate window just for appointments. You can walk past everyone else in line, and wait at the window to the far right. Someone will notice you right away and get you checked in.
I really like this new building as well. Spacious and with a lot of agents working. This experience was not bad at all. I still don't understand why so many people here in Vegas are all at the DMV, but at least now there are appointments!
