I recently rented a mini-van at Dollar - MCO, Hertz (my favorite) couldn't come close to the great rate that dollar had on mini-vans. I used the Rapid Rental Check-In, which shortened the time spent at the counter.
We were told to walk the aisle and select our choice. So, we looked at about 5 vans, all had scratches and high mileage. We photographed the van's condition before driving off. The return process was similar to Hertz's quick service, but the vehicle was a tad older than most Hertz rentals. Can't complain when I saved about $300 on this rental.
