Renting a car in the US is the most convenient.

The store staff were very helpful and did not try to upsell anything.

Very convenient and great value!

Overall it's quite good, with a competitive price. They didn't push any extra items when picking up the car. Since I was planning a road trip, I opted for roadside assistance at $5 per day, which is reasonable. Alamo is quite friendly about opting out of certain charges, like crossing the Golden Gate Bridge (north to south); if you pay online yourself, you can automatically opt-out of Alamo’s charges without contacting them. Picking up a car at San Francisco airport was quite intense, it felt like there were more people than cars, and you had to grab one as soon as it appeared.

Picked up the car in San Francisco using the self-service machine, which was quite convenient. However, you need to enter all the reservation details again, so the counter might be faster. No one tried to sell me insurance.
