Very good

All car rental companies are together, the queue was okay.

The car rental counter at the airport is large and very convenient. If you are under 25 years old, there is a young driver fee of $25 per person per day, which is very expensive. The fee is based on the birthdate on your ID, even being one day short won't exempt you. After negotiating with the counter staff, they said the young driver fee couldn't be waived but they upgraded our car for free. We got a Dodge Challenger, an American muscle car, which was awesome!

There are plenty of shuttle buses, so there's almost no wait. However, the counter staff will still try to upsell some additional services. There's a wide selection of cars in the chosen category. Haven't tried the self-service yet.

Alamo and other rental companies are located at the Las Vegas airport car rental building, about a 10-minute ride on a free shuttle bus. The office is large, and since we arrived close to midnight, there was no queue. Two counters were open, and we quickly completed the rental process. With the rental confirmation slip, you can take the escalator to the parking lot. There was only one car left in the booked category, and the staff let us choose any car from the higher category, but we didn't need a larger vehicle, so we took the only one available, which was very new with only 8000 miles on it. Returning the car was super quick, taking less than a minute, just a check to see if the tank was full. The rental building is only a 2-minute drive from South Las Vegas Outlets and a gas station, very convenient!
