This paper presents a case study of a community intervention aimed at reducing excessive drinking in young men on holiday in seaside camping resorts in the Netherlands. The self-regulated voluntary covenant of parties concerned was evaluated on the basis of several types of data (all collected in 2004 ): questionnaires administered to young men (N = 191), observations carried out by trained "peers," nuisance questionnaires among city center residents (N = 121), and interviews with local actors. Compliance with measures as well as the effects of measures are discussed. Limitations are noted and recommendations for optimizing the potential of community interventions are made.
