Given the choice between 7 days and waiting a year, I'd go with option 1 all day long. One thing you might consider is chartering out of St. Thomas (and I'd particularly recommend Waypoints), where the flights are both FAR cheaper and the schedules more flexible. In that case, you might look at a 9 day charter (Friday to Sunday). It really is a breeze to get from the USVI to the BVI from Charlotte Amalie on St. Thomas. Additionally, it will afford you a very convenient way to spend a day or two on St. John, either at the beginning or end of your charter.
