SUN, sand and sea, the picture is postcard perfect. At Kovalam though, it is incomplete. The hordes of tan-seeking tourists from across the seas, who placed the exotic beach resort on the world tourism map, are missing. And Kovalam is living the nightmare of every tourist destination: vast stretches of empty beach, unoccupied tables at restaurants, vacant hotel rooms and fleets of taxis begging for business. Tourist arrivals have dramatically plummeted, forcing the locals to seek refuge in anger and threaten agitation. And the winter of 1996 seems all set to herald a shake-up in the tourist arrival pattern in Kovalam and the way God's Own Country goes about the lucrative business of selling vacations to the world.
