We too opted for Curacao in place of our St Martin trip. We did a VRBO in Cas Abou Estates. It actually has its own very small private beach and is just a few minutes from Cas Abou beach. We spent most of our time on the Western beaches and Knip was probably our favorite but there were many beautiful beaches. Although I look forward to going back to St Martin and supporting the businesses there, I definetly hope to return to Curacao.
