NO NO NO.... Do the Dragon Flight Line!! LOL...
We did the zipline, its like 2500 feet down the side of a mountain and over the water.. I think you should be able to do both there..
you do tender and they have boats to bring you in. it was a great stop.. in my opinion better than st. maarten, thought i lived in st thomas for 6 months, so islands are islands to me. Bon Voyage.
