If you desire a room closer to the beach you will want accomodation in the Ocean Village part of the complex, the buildings with the 4000 series of room numbers. You may pay a bit more for the view. When you check in tell them you want a quiet area away from the "shows" and "disco". When do you plan on being there? Click on the attached link for more info.
Barcelo Bavaro Ocean Beach Resort?
