My family of 4 is going to PR in Feb and staying at the Hilton Caribe. We are interested in hiring a driver to take us to the Rain Forest, hiking there to waterfalls, the beaches in the NE area , perhaps the bioluminescent bay. Has anyone done this? How did you find someone? Is it less expensive than the formal excursions that run from the hotel? Or should we rent a car ourselves and go it on our own? Should car rentals, booking a driver, or the excursions be booked in advance? Or can we do it when we get there?
