My thought as well. Part of me thinks the Capt is joking, though I could be wrong.
My suggestion would to hitch a ride to Margaritaville and simply use this as an entrance to the beach. If you do not like the vibe head either direction on the beach and stop at a place that catches your eye. If you head left from Margaritaville you will head south and towards town, and have more options that if you hung a right and headed away from town.
