Overall very decent service. It's very easy to get in and out of here with your car. Just know that the entire rental car area is offsite from the airport so you do need to budget additional time getting in and out.
The service at the counter I would say was easily 4+ stars. They had me in and out relatively quickly all things considered. They did have to deal with another customer that was being irate about a drop fee charge. I give them credit for being so patient with an individual that was clearly being unreasonable with them.
I'm only dinging a point because of the car. I was in a full size car but the car was kind of a mess. You could tell a smoker had used it before. It had that smoker oder to it. My biggest issue though was that it clearly had an electrical issue. The dash and center display regularly malfunctioned while I was driving. There was one point where the digital display in the center just shut off. I could tell it's a wiring issuing because I literally smacked it and it clicked back on. Something is loose. Anyway one rough experience. Overall a good spot to rent a car in Vegas if you need one.
