I agree, in our 20 trips, we have never had a real problem with the ferry. I like landing in St. Thomas, usually by 1:00, getting off the plane and enjoying the smells and temperature of the islands. We normally catch the 2:30 ferry to Tortola.
We have flown through San Juan and even though we might land around 3 or so, we are stuck in the terminal until our flight to EIS. We have been stuck there for many hours because of flight delays. Hate not being able to get out and enjoy the islands right away.
