Altos de Chavon in La Romana is a beautiful place to hang out and a visit to our capital's colonial zone is also worth the trip.
you can do both as a guided excursion run by your touroperator or by rental car, what ever you prefer.
you will find rental car info at your hotel's front desk where the guest service is located, those guys will also give you a hand making the contact/phone call. we have several rent a car services in the area present at all resorts like avis, dollar, budget, national, alamo aso, rates vary depending on size of car ranging around $60.- - $70.- per day, it is highly recommended to pay a few extra bucks per day to cover a full insurance, don't forget to bring your drivers license, it's valid here during the time of your tourist-visa. always buckle up and don't use your cell phone while driving, tickets are expensive and specially during holy week the cops are looking for extra money. there's no problem to travel til thursday and enjoy the resort/beach over the weekend, good idea.
have fun
