They look a lot like some of the other websites I found for vacations in DR, like DR Nights, DR Mermaids, Blackbeards, etc.
If your are looking for a week with a chica with no hassles, and a safe environment I would say check out Satisfaction Plus Adult Vacations, or SPAV.

I was there a little over a month ago and I had a fantastic time. Room with private bathroom, food, drinks, laundry service, and a lady(s) of my choice at a price that will not break your bank.
They also have forums you can join for free where you will find tons of information and reviews from past guests.

The resort is in Juan Dolio about 30 to 45 minutes east of Santo Domingo.
