thank you CarolinaSailor!! Your vote of confidence for Voyage is all I needed. Is Sopers Hole near a ferry? Looking on-line it shows about a 30 min ferry ride from Tortola to STT. Assuming its on-time I was thinking 10:00am would be plenty of time. Arrive St Thomas at 10:30--taxi to airport by 11:30 at the latest. Would 2 hours not be enough time for carry on and Global Entry? Sorry I am truly starting here with a blank slate, and I want to maximize my time on the water and prevent a water taxi as its about $200 per person (one way).
Currently no 10am ferry but maybe by the time you charter it will change (likely it will). on weekends, you need every but of 2 hours at the airport. Most recommend 3 but the GE will help. Be sure you're comparing apples to apples. The ferry is well over $100pp these days so a $200 private boat is not as unreasonable as it sounds.
Check all these details closer to your trip.
