Hi, my husband and I are travelling to the D.R. this summer. We will be first in Santo Domingo and then we'll spend one week in Punta Cana. In between, we have 3 nights that we haven't decide what to do. We have read that Las Terrenas is very nice, but I do not if it is too long the way to go there, stay just three night and after that drive to Punta Cana ... What do you recommend us?
