You'll enjoy the Bali 5.4. It's our go-to for big groups. I suspect you won't need to refuel. I've only burned about half our supply for week-long charters, even with a fair amount of motoring and running the generator at night. Sounds like you are trying to pack a lot in at Jost Van Dyke for one day. May consider an extra day there - do Sandy Spit then grab a ball at Diamond Cay. Hike to Bubbly Pool. Spend the afternoon/evening at B-Line/Foxy's Taboo. Next day you can head over to Great Harbour and spend the day at the White Bay beach bars. Many dinner options ashore in Great Harbour.
