Sorry... bad advice !

Get a car and go to Sosua, Cabrete, Cabrerra and if you can take a couple of days (overnite) get to Samana and Las Terrenas
If you have never been to the DR, please do not try to rent a car and travel, especially to Samana or Las Terrenas !!
Please, however, feel free to do a search on this site for things to see and do. There is a wealth of info, it just depends on what turns your crank! Are you travelling with children, or are you looking for nightlife, do you want to swim with the dolphins???
Please search the archives, there is a myriad of things to see and do, but it is also depends on your tastes.
If you are curious on why I suggest not renting a car, do a search on that as well, as driving in the DR is not for everyone.
If you give us an idea of what kind of things you would be interested in, I am sure we can give you some ideas, but it would help if you narrow it down a bit.
Enjoy your trip,
Marlie
