We arrived with our vehicles at the ferry port in Barra with plenty of time to spare and booking documentation in hand. But this being Africa, we did not have a reservation. The ferry was full. There was room for us, but not the two vehicles. Eventually it was decided that we should get on with our luggage and the drivers would stay nehind and wait for the next ferry, which wasn't until the following day. Transport was arranged for us the other side to take us back to our hotel.
