If you do not want to rent a car, but would like to explore the area a couple of days during the week, I highly recommend the services of Danny or Jose. Danny and Jose are both professional Dominican Taxi drivers that can provide translation and transportation services. They both speak Spanish and English.  Their rates are very reasonable. They can be reached at 1-829-645-8285 (Danny) and 1-809-787-0856 (Jose; Villa Flamingo manager).
