For a bit of the REAL dominican republic be sure to take a day trip to Higuey where i live, it is only about 45 mins from dreams and a real eye opener, you will see plenty to laugh about. You will also pass through Higuey on the way to La Romana, if you would like some beautiful photos be sure to visit Altos de Chavon, a well known tourist spot. It is a replica 16th century village made from coral and it really is beautiful and the views of the river below are stunning, it is also rumoured to be where Michael Jackson and Lisa Marie Presley were married. But i believe the most interesting things to photograph are the people jut going about their daily chores, children in the street and so on.
You will no doubt get a few people willing to be your tour guide, but please be careful as on occasions they will try and take advantage of you. As i would advise anyone going to any unknown destination, keep your valubles secure and try and have a good idea of the exchange rate in your head if you are going gift shopping as nothing has a price and before you know it yourself or more likely on of your children has bought a worthless necklace for $50 or more.
Also if any of your children are female, keep them away from the male animation staff at the hotel, they are the peeps that organise the daily and nightly entertainment and can be very full on with the young girls, and the young girls usually for it! As long as you are aware of that you will be fine.
Ive rambled on but please if there is anything else dont hesitate to ask!
