We come from the west coast as well and go through STT about two thirds of the time. Like Manpot, we prefer the SJU/EIS route when it works out.....the variables being cost and if we have the flexibility to deal with potential flight cancellations on the short hop from SJU to Tortola vs the hassle of the ferry options. Private water taxi is a nice alternative to the ferries if you have a big group....otherwise its pretty pricey.

Starting this June, AA will have a direct flight to and from MIA and Tortola (EIS)....which means I can get all the way to the BVI in one stop. Game changer! Fingers crossed the new route works out.
