This was the worst car rental experience I've ever had in my life. The agency opened 30 minutes late. The one agent told us they had no cars for our 9am reservation and that we had to wait until cars arrived. When they finally arrived, at 11am, we were given a "free upgrade" but were now required to pay for extra insurance. Terrible. I will never be renting from Avis ever again in the Dominican Republic. Beware.
