My boyfriend and I have just booked a late deal - we're off to Punta Cana on Sunday! We'll be allocated our accomodation when we get there, but we know it will be one of three: Riu Mamba, Sunscape the Beach or what is now the Barcelo Premium (used to be Breezes). Can anyone offer any advice on what we should expect from these resorts, good or bad, and the surrounding area? Should we take both US dollars and Dominican pesos? What are the best excursions?
