Pruntrut banned non-Swiss non-residents from outdoor pool July 4 to August 31. Ban responded to overcrowding and repeated incidents by French tourists. French tourists showed inappropriate behavior, bad language, rule-breaking, woman-harassing, aggression. Post-ban security unnecessary. No bathing bans occurred. Seasonal passes sold doubled versus prior year. Conflicts dropped sharply. Atmosphere improved greatly. Revenues rose significantly. Ban temporary only. No repeat planned next season. Long-term milder solutions in works.
