The Costa Brava might be just as cheap these days, but for a lot of people, there's still nothing to beat the good old traditional holiday camp. In the week John Pitman visited a holiday camp at Selsey in Sussex, the place was booked out - 1,200 gathered together, all out to enjoy themselves. Well, most of them. You can't please all the people all the time. There were boys looking for girls, girls looking for boys. Confident people who mix easily; shy people who don't. There were families who come every year and those who had never been before - and some who won't come again. And always there, ever ready to make you smile, were the Blue-coats, personality-plus people: stars in their own little galaxy, but always hoping that some day someone will spot them, give them a break and take them away from it all.
