Lots of conflicting information on using your premium credit card for rental car insurance in the DR. After 5 rentals of long duration you can do so. The rental agencies now provide you with a form to sign so in the last couple of years the practice has become customary for seasoned travelers. Prior to that it was an argument with the rental car agent. However, your cc does not cover liability and not only should you have it, but most rental agencies require it. I’ve been paying about $9 per day for liability. Total per day last trip was $32.00. Also, I’ve rented at airports in Punta Cana, Santo Domingo, and Santiago. We don’t have direct flights to POP so my experiences may not be applicable locally.
In October, the battery died on a car I rented in SD. Fortunately I had rented from a major company. The car was replaced by their office at POP. Just imagine renting from a mom and pop company and having car trouble many miles away.
OK Motors has a great reputation but I’ve never rented from them. If you are staying within the local area, I’m sure they would be fine.
Another thing I’ve noticed is overall renting a car has become more customer friendly. They no longer hassle you about lots of expensive insurance.
The worst company to rent from been Sixt in Punta Cana. They won’t answer phones and are highly unethical.
