I chartered out of Puerto del Rey over Xmas and the charter company suggested a taxi driver, he kept in contact with us, we had some delayed flights, we stopped for lunch in San Juan at an amazing Deli, stopped and provisioned at Ralphs and arrived at the Marina before dark. With 5 of us it was $100 plus a generous tip and he took great care of us, suggested the Deli, waited at the provisioning stop and made good time on the roads.
He had a good size, well kept van. A rental car would never had fit 5 of us, gear and all the provisions in one trip.
