We learned both the scary and expensive lesson that the actual taxi drivers last call is 2:00. If you chose to stay longer you get a jitney. If the people we shared the van with didn't know this, we would have been left behind. Jitney drivers aren't allowed into the port so he tried insisting on dropping us at the ferry which was another $7 per person. He earned enough on 5 of us that the leader of our group told him he'd better be buying his wife a lobster dinner because that was what we were having for dinner that night for Valentine's Day.
