The staff requested self-registration, but the automated machine failed at the last step... It wasted my time, and in the end, I still had to queue for more than ten minutes.

The process was simple and convenient. However, I am quite upset about the inexplicable $30 fuel charge when I returned the car at San Francisco airport, especially since I refueled before returning it.

Friendly and simple procedures

You might have to wait in line for a while. However, if you're lucky, you can get a free car upgrade.

ALAMO's basic services are adequate, with shuttle buses and decent online customer service. However, they didn't provide sufficient information about the car and its location. The parking lot staff were also inadequate and unclear, merely suggesting to pick any car. Follow-up inquiries about refueling were difficult as their phone lines were almost never answered.
