Unless you do the water taxi, your options will be limited by the ferry schedule. I can only see three options on Sunday: Smith (Tortola Fast Ferry) at 2:15, Road Town Fast Ferry at 4:15 and Smith again at 5:15. Add a minimum of 45 minutes for Smith to get to West End and an hour for RTFF to Road Town. Add Customs & Immigration time to those times. The bottom line is it will be very limiting using the ferries. If they can make the first ferry to West End, Little Harbour JVD sounds feasible. Other anchorages on JVD may be full and Norman may be full with first nighters. Soper's Hole could be a default option for your first night.
