Route 66, then around the US, north to the Canadian border, and south to the Mexican border, a total

Quite good

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 self-service process is cumbersome. It felt like I had to pay again after already paying. It's confusing.

At Los Angeles Airport, you need to take the Alamo shuttle bus, which takes about ten minutes. The process went smoothly, although immigration took a bit longer. The car rental procedure was easy and you could choose from cars in the same category. Luckily, after some deliberation, we chose a GMC SUV instead of the originally booked Grand Cherokee. Returning the car in Salt Lake City was super convenient. Follow the Rental Car Return signs at the airport, park the car, and an employee will scan the vehicle with a handheld device, and that's it!

The staff at this Alamo location will try to sell you insurance and other services you didn't purchase. It's up to you to decide whether to buy them or not. The problem is: I booked a 'compact car' (Nissan Versa or similar) through Zuzuche, and the staff said it was too small (I only have two people) and suggested upgrading to a higher class for an additional fifteen dollars per day. I agreed, but when I went to the garage, I got a 'Ford Focus,' which is also listed as a compact car on Zuzuche's website. Why did I pay extra for an upgrade yet still get the same class of car? I think this location takes advantage of renters' unfamiliarity with car models to deceive them into paying for unnecessary upgrades. I've rented from many companies through Zuzuche and have never encountered this problem elsewhere.
