Avis is not showing any availability for a van in St Marten on the day we are there. We need to move seven people around. I can get two cars for about $60 for the day. How close is the Avis desk to the port? Any other rental companies that have vans that folks have experience with? The other option I can think of is to try to hire a taxi for the for the day. How much? We want to hop around the Island.
