Fair enough - being picked up is good. You should get to the Rhone, off Salt I. in the BVI. Best dive in the region, whatever Low Key tells you. If Low Key won't go, try Cruz Bay Water Sports. I haven't checked this year, but they have almost always gone on Fridays. I WILL be checking, because we want to book it for Friday Jan. 22, if possible (and probably for 2 succeeding Fridays.)
You need passports as well as c-cards.
