We are doing something quite similar on our next trip...

First four days in Negril and then eight days in a villa in Silver Sands. Silver Sands is in the town of Duncans (between Mo Bay and Ochi). We get to have all the fun of Negril for a few days and then chill out for a week in a lovely villa.

My only fear is that no one will want to leave Negril!!!!
