We've only done the islands twice - the last time was ATL to SJU to Tortola, and it was a very long tiring expensive trip.

Our 2016 plan is not rush or worry about the ferry connections from STT to the BVI. We are planning a day in STT before the ferry over, and day in STT before we leave to allow us time for the ferry over.

I distrust the airlines' abilities to give a flying fig about our connection needs.
