Honestly, unless everything is truly closed down, there will be ferries from Saint Thomas to Tortola. Maybe not Virgin Gorda, but Tortola. It's how the economy operates and they're always busy enough to justify the trip. We had a long but trouble-free trip in February that involved a connecting flight, a taxi to the ferry dock, a ferry to Tortola, a taxi to Trellis Bay, and a ferry to Virgin Gorda. A delay anywhere might have messed it up, but we had time for a convivial dinner with people doing the same thing at Trellis Bay--and once you're there, you're on Virgin Gorda, one of the most relaxing places anywhere.
