Look at your left hand.
The bottom of your pinky finger is where you are
If you fold down your thumb alongside your index finger the bulge is where the mountains are. Also the heel of your and and the index finger.
In other words, all of them are a long way away.
You could get a car and driver--do not drive!--and go to some place like El Seibo...or, now that Ithink about it, maybe Sabana de la Mar...it is on Samana Bay...out of the way, rural, very Dominican and not touristy (well Sabana de la Mar is a little touristy now, but not much) at all. Sort of difficult drive but doable in one day.
Eat local...Fried fish or filete and tostones are good everywhere. Beer is cold and cheap. Have your driver find out where to eat.
Do not dress in shorts. Long pants, collared shirt, shoes and socks. Jeans are best for you both. T Shirts are cool, too. hats sunglasses, bug sprayand sun block...
You will have a blast!!
