Very convenient.

Still tried to upsell various things.

It's unbelievably bad, they try to scam you at every opportunity. Charged us hundreds of dollars upfront and refused to refund even after we declined additional services. They inexplicably charged city taxes at $75 per city, and an extra $60 for returning the car one hour late. The worst part was trying to replace our rented luxury SUV with a regular Nissan. After refusing, we were made to wait a long time, only to find several matching models in the parking lot. Truly a dishonest rental company with no merits! We still haven't received several thousand dollars back!!!

They didn't accept prepaid credit cards which was extremely frustrating.

Would not use Dollar again. Alamo are better. The car had a built in Sat Nav which they didn't advise us of so we paid for extra for a Sat Nav at almost $10 a day including tax which we didn't need. Got stuck in traffic so returned the car 2hrs later than specified and ended up paying for another day hire.
