Alamo at San Francisco Airport has many counters, the speed was acceptable.

The wait time was a bit long, but the staff was persuaded to upgrade our Kia to an Enclave.

Very good

The company's service is efficient. Even though they recommend some insurance options when picking up the car, the final decision is up to you. Although the Dodge I reserved was not available, I could choose an equivalent model. What surprised me was how easy it was to return the car. You almost just need to drive there and hand over the keys.
