I have used Dollar and National for many years. However, I do tend to stay with national now that we are executive aisle members. But we have never had a problem renting with Dollar either. My daughter used them last October and got a great deal on a minivan. The only negative thing I can say about dollar was the times we did rent through them, they did try to upsell us to a bigger car. Both companies are located at the airport so very convenient.
