If you are staying for more than 3 days, I highly recommend renting a car and spending the day at Luquillo beach! Its my favorite beach and they serve some bomb home cooked Puerto Rican food on the strip! Go early, the parking becomes INSANE. 9am is good.
Visit Ponce
Its a beautiful city. Rent a car and head out early. Parking is crazy, but worth it. Plenty of shops, good food and beautiful architecture.
