It's acceptable.

Excellent

The process was very simple, and the wait time was not long. The return process was so convenient that I was concerned and asked the front desk if it was really all done.

The attitude was mediocre, and they tried to upsell me on additional costs. The main issue was that I booked a Chevrolet Suburban, but they gave me a much smaller Chevrolet Tahoe. When we raised our concerns, the DOLLAR staff said expressionlessly that they didn't have any Suburbans! It's frustrating to deal with such a situation.

The service was mediocre. They didn't have the Nissan Altima mid-size car I reserved, and there was no free upgrade or any explanation. They just kept insisting that the Nissan Versa was the car I rented. Another friend who rented with me faced the same issue: he reserved a Ford Focus but was given a Hyundai Accent. It seems that not providing the reserved car model is very common with Dollar.
