There is taxi service from the airport to the hotel. Depending on how many people are in your party and the amount of luggage, the fare may vary. Do not expect to pay under RD $100. The hotel is approximately ten miles from the airport, 20 minutes.
Also, you may want to ask if an airport transfer is included in the travel plan package you have arranged to the resort. No sense paying for a taxi, if you have a transfer as part of your package.
The hotel: see the reviews from "Debbies Dominican Republic Travel Page" and DR1.
