The process was straightforward.

They kept pushing upsells—insurance, car upgrades, fuel fees, etc. I was talked into buying additional insurance by the front desk, even though it was only around 100 dollars, it was quite annoying. I thought the insurance included in my order was comprehensive, but their 'full insurance' was actually just an extra coverage similar to full insurance in other rentals. In the end, Alamo added another super coverage. This was the third Alamo I encountered during my trip at San Francisco airport, the previous two didn't ask these questions. Overall, the worst experience of this trip!

Both pick-up and drop-off processes are quite convenient, there is no pressure to purchase insurance, and there is a good selection of vehicle models.

Overall, it's acceptable. Picking up and returning the car is quite convenient. Especially the phone service desk, as they will provide a Chinese translator if your English isn't good, and they are very patient. However, I initially booked a full-to-full fuel policy, but they gave me a full-to-empty one. I didn't notice at first, so I ended up buying a full tank for over 50 dollars. Additionally, they charged me another 9 dollars at the return, without clear reason.

There are few rental locations, but it's sufficient. In the USA, renting a car is a must because taxis are too expensive.
