We go to St. John a fair amount, especially when we are there for more than a week. It's an easy process, we just find its not worth bothering if we've only got a week since a week is barely enough time to circle the BVI. With 9-10 days, we can easily circle the BVI and spend a couple days in St. John.

Last November actually with only a Sat-Sun trip, we were on Tortola early morning and off the docks by very early afternoon and on our way to St. John where we were picking up a few more crew. We spent Sat and Sun night in St. John before heading back to the BVI for the rest of the trip. It's one of the shortest trips where we actually visited St. John and it actually worked out great - mainly because we headed there right away - I think we just motored too as it was a very long travel day (starting the Friday night before..)
