We (2 adults) will come to the Island for one week, and will be needing transport from Santo Domingo to La Romana, and stay there for 2 nights. Then travel for 2 nights to Punta Cana, and then for 2 nights to Las Terrenas. After that we go back to Santo Domingo for 1 night. Is it wise to rent a car and do this on our own, or is there a company that rents cars with drivers? Or is it maybe even cheaper to just get the transfers. I don't want to travel with Bus, because I want to be able to stop for sights along the way. I read that the drive from Punta Cana to Las Terrenas will be a long and not too easy drive. And I guess this is my only concern for a simple rental car. I guess there is no GPS map out there. Any advice? Or contacts? Thanks for any help.
