I tried to respond to your question re the airport in the BVI people talk but not sure I understand the question.
Regarding car rentals, just go to the TTOL sponsors list and pick one! <img src="http://www.traveltalkonline.com/forums/images/graemlins/Smile.gif" alt="" /> Again, you should hustle with that! February is technically before Heineken though, as it's a bit later this year. You don't need 4 wheel drive at all. Just get a beat up corolla like everyone else does.
